RailAdventure

Updated: August 2026 – Sometimes a train goes past that just doesn’t fit: an older electric locomotive, behind it two short, unremarkable wagons, and right at the back a brand-new multiple unit with taped-up windows. Not a freight train, not a passenger train — a transfer run. The entry RailAdventure in this database stands for exactly this field: workings in which the vehicle isn’t the means of transport, but the cargo.

What is RailAdventure?

RailAdventure is an entry in this EVU database listed under Germany. The name combines the English word for rail with “Adventure” and is written as one compound word with internal capitalisation — a spelling worth bearing in mind when looking it up, because directories treat it differently.

In this database, the entry is assigned to the segment “other”. That’s not a dodge but an accurate classification: transfer and special workings are neither freight nor passenger traffic in the classic sense, and not infrastructure construction either. They form a field of their own that simply isn’t provided for in the usual segment grids. Which services an individual company currently provides in this field changes with contracts and approvals — always check the current status.

Why a vehicle runs without a load

Rail vehicles are built where manufacturers such as Siemens Mobility have their works, and used where they’re needed — often hundreds of kilometres apart. Road transport is usually ruled out because of weight and clearance. So the vehicle runs on its own wheels, but not under its own power.

For spotters this is the chance to see vehicles that would never otherwise appear in this location under normal operation. The guide to good train photos covers how to handle such subjects photographically.

Adapter and coupling wagons: the transfer specialist’s tools

The most unremarkable part of a transfer train is often the most important. Adapter, coupling and buffer wagons solve exactly the problems a consist would otherwise fail on.

Vehicle in the consist	Task	How to recognise it
Hauling locomotive	pulls the consist, provides braking and train protection	at the very front, usually an older or general-purpose electric locomotive
Adapter wagon	connects different couplings and lines	short wagon, often with a conspicuous structure
Buffer wagon	keeps distance between the locomotive and sensitive cargo	empty flat wagon with no obvious purpose
Transferred vehicle	the actual cargo	taped up, lowered pantograph, dark cabs
Escort wagon	space for accompanying staff	passenger coach or engineering-train wagon at the rear of the train

Not every transfer train includes all of these building blocks. But as soon as something stands between the locomotive and the target vehicle that clearly isn’t carrying a load, it’s very likely there for a technical reason.

Towing run with a cold locomotive

A special case is a locomotive that’s itself being towed. “Cold” means: the drive is out of operation, often the auxiliary systems too. The vehicle rolls along and, ideally, brakes along too — which is why the crucial question before any towing run is whether and how the towed vehicle’s brake can be integrated.

That’s where the restrictions you see out in the field come from: lower maximum speed, sometimes an escort on the towed vehicle, occasionally extra stops. Classic hauling locomotives for such tasks are general-purpose older machines such as Class 139 or Class 111; on non-electrified sections, powerful diesel locomotives such as Class 232 take over. Which machine is actually piloting depends on the job and on availability, and changes constantly.

Vehicles for such assignments often come from hire and pool fleets. Examples in this database include Eurailpool or Rent-a-Rail; transport and service providers such as RTS Rail Transport Service show how fluid the boundaries between traction, technology and logistics are in this market.

How to document a transfer run

The typical mistake is the collective note. “Transfer with a new vehicle” helps no one later — not you, not anyone else. It makes sense to record the vehicles one by one in their actual order.

The guide to reporting sightings describes how to turn this into a report others can use.

A word of caution on interpretation: from the outside it’s rarely clear who’s all involved in a transfer working. Manufacturer, keeper, executing operator and recipient can be four different addresses, and on the vehicle you only see one of them. So record what’s written on it, and leave open what you can’t read. Especially with new vehicles that don’t yet carry complete markings, an honest gap in the note is worth more than a plausible guess that no one can check later.

Common mix-ups

• Engineering train mistaken for a transfer run — engineering trains are also short and mixed, but they carry materials or machinery.
• Light-engine move mistaken for a towing run — several coupled locomotives often run under their own power; what matters is whether one of them is running cold.
• Adapter wagon mistaken for a freight wagon — it transports nothing, it connects.
• New vehicle mistaken for a heritage vehicle — wrapping and missing markings look similarly unusual in photos.
• Hauling locomotive noted as the keeper of the whole train — every vehicle in the consist has its own data panel.

Conclusion

Transfer and special workings are the opposite of routine: short consists, unusual combinations, vehicles that would otherwise never be in this location. Anyone who recognises them has, with a little attentiveness, access to subjects and sightings that appear nowhere in the timetable. The rule stays the same as everywhere: read first, then note it down, then interpret.
