Key takeaways
- RP Eisenbahn works on the infrastructure side – it's about tracks and operational management, not long-distance train services.
- An EIU runs no passenger trains of its own. It provides facilities on which others operate.
- Small networks are legally independent: their own rulebook, their own contacts, their own house rules.
- There's no dependable public source on size and network extent – so we deliberately give no figures.
- What matters for you is the boundary on the ground: where the federally owned network ends, responsibility and access change.

How to recognise RP Eisenbahn
Does the train really belong to RP Eisenbahn?
- Unfamiliar signs at the track – notice boards, shunting signals and marker boards deviate from the usual picture
- No vehicle carries a company logo in regular service – infrastructure shows itself on the ground, not on the train
- Small shunting locomotives and older diesel locomotives in shunting duty rather than modern main-line machines
- Transfer points, where trains stand still and the locomotive changes
- Fence, gate and access sign mark the boundary between public area and operational railway land
- Route maps often show such sections as independent infrastructure
Strengths and weaknesses
What the company stands for
- Small networks bring unusual vehicles into view that never appear on main lines
- Transfer points are predictable: trains stop there regularly and for a long time
- Siding tracks often run alongside public roads and can be photographed legally
- Knowing the responsible party means you already know who to ask
Where it falls short
- There's hardly any dependable public information about the company itself
- Network extent, fleet and range of services can't be reliably estimated from outside
- On foreign networks, local instructions apply that you, as an outsider, don't know
- Operational railway land often looks open, but isn't – which regularly leads to conflicts
Updated: August 2026 – Every spotter notices it at some point: a track branches off from the main line, the signs look different, and the train standing there belongs to no company you recognise. This is exactly the area RP Eisenbahn works in – as an infrastructure and service company away from the federally owned network. Publicly there’s little documented about the company itself; about the world it works in, a great deal.
The small facilities belong in the logbook too
Record location, vehicle number and time – on secondary networks especially, you'll otherwise never find your way back.
What an infrastructure company is – and what it isn’t
The central dividing line in German railway law runs between two roles. A railway infrastructure manager owns and maintains tracks, points and signals and sells paths. A railway operator runs trains and needs its own licence to do so. One company can do both in separate entities, but the roles remain distinguishable.
For spotters this isn’t a formality. It answers three questions at once: who’s allowed to run here, who decides on access to the site, and who an enquiry should be addressed to. Filing a facility away as “something to do with rail” loses exactly this information.
Why we don’t name figures here
For many small infrastructure and service companies there’s no reliable public data. Route kilometres, fleet sizes and staff numbers circulate in outdated versions or come from self-promotion. We deliberately do without them.
That’s not a shortcoming but a method: a sighting isn’t improved by adding a figure you can’t substantiate. What you can substantiate is everything you see at the track – and that’s entirely enough for a clean logbook.
You recognise the boundary on the ground
Network transitions are almost always visible: a change in sleeper type, a different signal aspect, a marker board in an unfamiliar form, a gate. Photograph this spot too – it's the best evidence of which network your sighting took place in.
The last mile: how a wagon gets to the works
| Section | Who provides the track | Who operates | What you see there |
|---|---|---|---|
| Main line | large network operator | main-line locomotive of an EVU | fast through traffic |
| Hub or marshalling yard | network operator | shunting sections | train breakdown, long dwell times |
| Transfer point | network operator and siding | locomotive change | brake test, paperwork, standstill |
| Siding track | facility operator | small locomotive or industrial diesel | slow movements, often at walking pace |
| Works site | the business itself | works vehicle | barely visible from outside |
These five rows explain why a single freight wagon can be moved by four different companies on its journey. Anyone who only notes the main-line locomotive has documented the shortest part of the trip.
You can see what this looks like in operation at the big hubs. At Duisburg-Hochfeld Süd and Hagen-Vorhalle, main-line traffic and transfers run side by side; Hamm (Westphalia) additionally shows the switch between passenger and freight traffic. Companies such as Rurtalbahn or Captrain Deutschland serve traffic there that couldn’t happen without this small-scale siding level at all. Choosing the right time of day is explained in the article on tracking freight trains live.
How to approach an unfamiliar network
Check the map on site
On open map services, private networks are usually drawn in as independent infrastructure. The OpenRailwayMap guide shows how to read that.
Look for public viewpoints
Road bridges, level crossings and footpaths are almost always enough. Where no public path leads, it isn't a spot.
Observe operating times
Siding traffic runs as needed, often daily at the same time. Two observations are usually enough to establish a pattern.
Note the vehicle number
Small shunting vehicles change keeper more often than large main-line locomotives. Without a number the sighting is worthless later.
Document the responsible party
Record which network you observed. That information is more stable than any company name.
Is your sighting on a foreign network properly documented?
The location matters most – without it, even the best number is worth nothing.
Secondary networks are under-documented
That's exactly why your reports there are valuable. Log them while the facility is still in operation.
Access, house rules and the invisible boundary
The location is unproblematic, if …
- you're standing on a public road or bridge
- a platform is regularly accessible
- a fence or ditch lies between you and the track
Check first, if …
- a path with no sign runs directly alongside tracks
- a works gate stands open but no one is visible
- a level crossing carries a private sign
Don't enter, if …
- signs mark it as operational or works land
- you would have to cross tracks to get there
- the area visibly belongs to a facility of a business
The point is simple but constantly underestimated: on a private network, the house rules of the respective operator apply, not those of DB. And that operator knows neither you nor your hobby.
Operational land rarely looks like operational land
Siding tracks run through industrial estates, across roads and between sheds. The transition from public to private is often just a sign, or nothing at all. Stick to paved, obviously public paths – the consequences of the alternative are set out in Trespassing on tracks, and Is trainspotting allowed? helps further.
Verdict
RP Eisenbahn stands here as representative of a whole category: small companies working on the infrastructure side, hardly visible publicly, and yet deciding whether a wagon reaches its destination. Writing about them means writing about responsibilities, not about vehicles.
For you at the track, the practical rule remains: first clarify whose network you’re looking at, then photograph. In that order, not the other way round.
Verdict in brief
An infrastructure and service company away from the federally owned network. There are no dependable public figures – the practically important information is a different one anyway: whose track is this?
Document what no one else documents
Siding tracks disappear quietly. Your sighting today is a source in ten years.
Summary
- The German rail market doesn't consist of just one big network, but of many small ones connected to it.
- Companies like this are why a freight wagon ever reaches the works at all – the last mile is rarely run by the big group.
- Ignoring the infrastructure level means being surprised by unfamiliar signs, unfamiliar locomotives and suddenly blocked paths.
- Where the source situation is thin, an honest gap in the sighting log is worth more than a guessed entry.
Frequently asked questions
What exactly does RP Eisenbahn do?
The company works in the field of railway infrastructure and railway services. There's no dependable public source on network extent, fleet or individual facilities, so we deliberately give no figures here. What can be described is the role: infrastructure managers provide tracks, transport operators run trains on them.
What's the difference between an EIU and an EVU?
A railway infrastructure manager owns and operates tracks, points, signals and often the stations. A railway operator runs trains and needs its own licence to do so. The two have been separate since the rail reform – which is why trains of many different companies can run on one network, as happens daily at Germany's largest network operator, DB InfraGO.
Who actually owns siding tracks?
Usually the industrial firm, port or municipality on whose land they sit. Operational management is then often taken on by a specialised company. This is exactly where the common confusion arises: the owner of the track, the operator of the facility and the company moving the wagon can be three different parties.
Who holds the house rules on a private network?
The respective operator of the facility – not the Federal Railway Authority and not DB. That's practically relevant: a path that looks like a public field track can be operational railway land. The basics are explained in the article on House rules at stations and operational railway land.
How do I recognise that I'm looking at a foreign network?
By the details on the ground: different notice boards, different marker signs, gates with company names, often a crossing with a buffer stop or barrier. On maps such sections are usually entered as independent infrastructure – how to read that is shown in the OpenRailwayMap guide.
What vehicles do you see at such facilities?
Mostly shunting and transfer vehicles: small locomotives, older diesel locomotives and industrial machines. Typical classes from the V100 family include Class 293 or industrial diesels such as Class 273. How to tell such older diesel machines apart is covered in Identifying older diesel locomotives.
Am I allowed to photograph a siding track?
From public paths, roads and bridges, generally yes. On the operational land itself, not without permission. The boundary is often poorly marked, so the rule is: when in doubt, don't leave the public area. The distance rules are set out in Safe distance from the track.
Why does a freight train stand so long at a transfer point?
Because that's where the network and hence the responsibility changes. The train is handed over, paperwork and a brake test follow, and often the locomotive changes. For spotters that's a gift: hardly anywhere else does a vehicle stand still so long and so legibly.
Where can I find reliable information on small infrastructure managers?
In official registers of the supervisory authorities and in the operators' own network access conditions. Press articles and company websites are often out of date. When documenting a sighting, it's better to note the observable facts – location, vehicle number, time – than an attribution you can't substantiate.

The operational level in the railway operator database
Who actually runs the trains, with keeper markings and identifying features on the vehicle.
Rurtalbahn GmbH
Rurtalbahn GmbH operates on lines in western Germany. This page explains a feature typical of such lines: the level crossing.
FreightCaptrain Deutschland GmbH
Captrain Deutschland is a freight operator that trades as part of a brand family. That's exactly what makes identification in the field interesting: brand, keeper and operator often don't match up.
FreightMitteldeutsche Eisenbahn GmbH
Mitteldeutsche Eisenbahn stands for freight traffic with an industrial background. This page explains field identification and the railway's own power supply system.
Typical vehicles
Class 273 (G 1206)
The Class 273 covers locomotives of the MaK/Vossloh G 1206 type: four-axle diesel locomotives with a centre cab, widely used by private freight operators.
ClassClass 293 (V 100 East)
Class 293 covers re-engined conversions of the DR V 100: four-axle diesel locomotives now running mostly for private operators and on engineering trains.
ClassDB Class 203 (V100)
The Class 203 are re-engined East German V 100 locomotives – today running mainly with private railway companies. Here's how to recognise them and tell them apart from the original vehicle.
ClassMaK 650 C
The MaK 650 C is a three-axle shunting locomotive with a rigid frame. Many machines in this group have been retrofitted for radio remote control – and it shows.
Where you will find RP Eisenbahn
Spotting locations where you will regularly come across vehicles from this organisation – with viewpoints, the best light and coordinates.
Duisburg-Hochfeld Süd
Duisburg is the freight hub of the Ruhr region, and Hochfeld Süd is the point where the trains cross the Rhine. If you're after heavy freight trains, port traffic and locomotives from private operators rather than ICE units, you'll find one of Germany's busiest freight lines here.
Freight hubHagen-Vorhalle Marshalling Yard
Hagen-Vorhalle is one of Germany's large marshalling yards, sitting at the northern end of the Ruhr-Sieg line. Observation is strictly from public roads and bridges – accept that, and you get to see operations that modern freight hubs no longer show.
Junction stationHamm (Westf) Hauptbahnhof
At Hamm, the Ruhr region's great routes go their separate ways: towards Hanover, towards Münster and towards Kassel. Add to that a freight share that hardly any other German main station of this size reaches – and a platform hall that ties the whole operation together.
More companies
DB InfraGO
DB InfraGO has been Deutsche Bahn's infrastructure company since 2024: network and stations under one roof, oriented towards the public good. It doesn't run any trains – but it decides where you're allowed to stand and which line is currently closed.
InfrastructureEisenbahn-Bundesamt (EBA)
The Eisenbahn-Bundesamt is a public authority, not a railway company. It authorises vehicles, issues safety certificates and supervises the federal railways. It owns no track, runs no trains – and it's the wrong address for photo permits.
InfrastructureRegio Infra Service Sachsen
Regio Infra Service Sachsen operates railway infrastructure away from the federally owned network. The company runs no passenger trains, but it decides who's allowed to run on its tracks – and who's allowed to be on its premises.
InfrastructureEisenbahnnetzwerk Bremen/Niedersachsen (EBN)
Between the Weser, Elbe and Ems lies a second rail network: regional railway infrastructure that doesn't belong to the federal government. The EBN stands for this layer – track without trains of its own, shaped by seaport hinterland traffic, private sidings and its own set of rules.
