Key takeaways
- The KRC is a railway slewing crane: a crane on a rail undercarriage, not a converted mobile crane and not a locomotive.
- Fastest way to identify it: slewing upper carriage, jib, counterweight, outriggers.
- Typical tasks are transporting points, bridge assembly, material handling and recovering derailed vehicles.
- The type number denotes a lifting-capacity class at Kirow, not a class in the sense of locomotive numbers.
- Keepers change: cranes often belong to construction firms or recovery services rather than the infrastructure manager.

Identifying features
Is this really the class in front of you?
- Slewing upper carriage with jib on a railway undercarriage - the most distinctive silhouette of any departmental vehicle
- Clearly visible counterweight at the rear of the upper carriage
- Side outriggers that are extended during working operation
- Warning livery in yellow or orange with contrast stripes and beacon lights
- Often coupled to protective and jib-support wagons on which the stowed jib rests
- Twelve-digit vehicle number with type code 99
Updated: August 2026 - Hardly any departmental vehicle is as unmistakable as a railway slewing crane. Upper carriage, jib, counterweight: you can recognise this silhouette from a hundred metres away. Kirow’s KRC series cranes are among the machines that turn up exactly when something needs to be lifted rather than driven in track engineering - and this page shows you how to place them.

What is the Kirow KRC 810 / 1200?
The KRC 810 and the KRC 1200 are railway slewing cranes from the Leipzig crane works: crane machines whose lower carriage is a full railway undercarriage complete with buffers and a coupling. The upper carriage, with its jib, drive and counterweight, can slew relative to the undercarriage, and side outriggers absorb the tipping forces during working operation.
The number in the type name distinguishes lifting-capacity classes within the crane family - it’s not a class number in the sense of locomotive designations and shouldn’t be read as one. Anyone who wants to unambiguously identify a specific machine needs the twelve-digit vehicle number. How its structure works is explained in the article on the UIC number and its check digit.
How to reliably identify a railway crane
Look for the upper carriage
A superstructure that slews relative to the undercarriage is the defining feature. Every other track engineering machine has a fixed superstructure.
Jib and counterweight
In transport condition the jib lies flat pointing forward, with the counterweight sitting opposite at the rear of the upper carriage. Together they produce the typical asymmetric silhouette.
Check the outriggers
Extendable outriggers sit on the sides of the frame. When they're extended, the machine is working; when retracted, it's in transport position.
Look at the undercarriage
A pure rail undercarriage with buffers - no rubber tyres anywhere in sight. That's what separates the crane from a road-rail excavator.
What crane work stands for in the construction process
Track engineering mostly consists of machines that work in the direction of travel: tamping, cleaning, ploughing, rebuilding. Such special-purpose vehicles are built by firms such as Gleisbaumechanik Brandenburg. The crane is the exception. It works across the line and lifts loads to places no track leads to.
| Construction task | Why a crane is needed | What it replaces |
|---|---|---|
| Installing or replacing points | Points assemblies are heavy and mustn’t be twisted | Breaking them into parts and days of manual assembly |
| Bridge and retaining-wall work | Components must be moved beyond the track centreline | Mobile cranes, for which there’s often no access |
| Recovering derailed vehicles | Vehicles must be lifted and set back on the track | Elaborate lifting and pulling gear at ground level |
| Loading rails and sleepers | Precise placement next to the track | Manual loading with high staffing needs |
| Emergencies and special cases | Short-notice availability of heavy lifting capacity | Improvised solutions with long possession times |
Material transport in the narrower sense, by contrast, is handled by other vehicles: the Plasser & Theurer MFS 100 as a conveying and silo unit in the works train, or a track maintenance vehicle such as the Robel GKW 315. For smaller lifts away from the line, the Liebherr A 900 C ZW-Li/1031 as a road-rail excavator is, in turn, the more flexible tool.
Works trains appear at short notice
Keeping an eye on other spotters' live sightings helps you find out faster where something unusual is currently standing.
How a crane operation unfolds
A crane operation isn’t a spontaneous event, but a planned possession with a clear sequence, whose worksite is secured by service providers such as BahnService / Safetrail. Knowing the sequence lets you read a worksite from outside far better - and tells you whether something is happening right now or the machine is simply waiting.
First, the crane is transferred to the worksite, usually as part of a train with protective and jib-support wagons. On site, the jib is taken out of its transport position and raised; the side outriggers extend and brace the machine against the tipping forces. Only then does the actual lifting work begin - for example, raising a points component, which is then slewed and set down precisely. After the final lift, everything runs in reverse: stow the jib, retract the outriggers, uncouple, depart.
For observers, one detail is decisive: a crane with its outriggers extended and its jib raised is working. As long as the jib lies flat on the protective wagon, the machine is in transport condition and will move again before long - but it won’t lift anything.
Number, keeper, and what changes about them
The crane, too, carries a twelve-digit vehicle number starting with type code 99 - the code for departmental vehicles. What follows identifies the keeper’s country and the vehicle, closed off by the self-check digit.
More important than any type number in practice is the keeper’s marking. Railway cranes often belong to construction firms such as SPITZKE SE, recovery services or leasing companies; markings, liveries and areas of operation change with contracts and ownership changes. So when you document a sighting, always note the current marking alongside the number - that keeps the entry usable years later. How to build such a log is shown in the guide to keeping a sightings log.
Photography: distance is no drawback here
The danger zone is bigger than the machine
During crane work, loads swing beyond the outline of the vehicle, and the worksite often operates at night under a possession. Tracks, worksite areas and operational railway installations are off limits - even when nothing seems to be happening. Machines can start moving without warning.
Photographically the crane is rewarding, because its silhouette stays legible even from a great distance. That’s exactly why it works better from bridges and public paths than many other departmental vehicles:
- Choose a side view. Only from the side can you see the jib, the upper carriage and the counterweight as a whole - from the front, the shape disappears.
- Watch the outriggers. A shot with the outriggers extended tells a working scene, one without shows only a stabled vehicle.
- Choose your focal length deliberately. From a safe distance you need a telephoto lens; which optics make sense for that is covered in the guide to the best telephoto lens for railway photography.
- Know the rules beforehand. What’s permitted at the track and what isn’t is set out concisely in the rules on safety distance at the track.
Common mix-ups
It points to a railway slewing crane if …
- the superstructure slews relative to the undercarriage
- a jib and a counterweight are present
- side outriggers sit on the frame
- the vehicle has buffers and a coupling
Look more closely if …
- the jib rests on a coupled protective wagon and that's all you see
- the machine is being transferred as part of a train and stands between freight wagons
- an excavator with a long jib sits on the track - it could be a road-rail vehicle
It isn't a railway crane if …
- the vehicle sits on rubber tyres with the rail wheelsets raised
- the superstructure is fixed to the frame and doesn't slew
- working attachments sit close above the rail - then it's a track maintenance machine
Verdict
The Kirow KRC 810 and the KRC 1200 stand for the heavy-lifting side of track engineering: wherever points are lifted into place, bridge parts are moved, or derailed vehicles are recovered, a railway slewing crane is unavoidable. Thanks to the upper carriage, jib and counterweight, identifying it is as easy as with hardly any other departmental vehicle - the harder part is getting to see the machine at all.
In short
A slewing upper carriage plus jib plus counterweight on a rail undercarriage: that's a railway slewing crane. The type number marks the lifting-capacity class, the vehicle number with a leading 99 the individual machine.
Rare sightings deserve an archive
A crane operation might pass by once a year - with Traintrack, the documentation doesn't get lost.
Summary
- Railway slewing cranes are the heavy-lifting tool of track engineering - deployed wherever loads must be lifted rather than rolled.
- The silhouette of upper carriage, jib and counterweight makes the Kirow crane unmistakable.
- In transport condition the jib rests on its own protective wagon - an image that's easily misread.
- Crane operations take place within a possession of the closed track; observation is only ever from outside it.
Frequently asked questions
What is a Kirow KRC 810 or KRC 1200?
A railway slewing crane: a crane whose lower carriage is a railway undercarriage, letting it move on the track. The upper carriage is slewable and carries the jib, drive and counterweight. Such cranes lift points, bridge parts, vehicles and heavy material in the track area.
What does the number in the type name mean?
At Kirow it denotes the crane's power, or lifting-capacity, class - a KRC 1200 therefore belongs to a higher class than a KRC 810. It's explicitly not a class number in the pattern of locomotive designations. The unambiguous identifier is the twelve-digit vehicle number.
What is a railway crane needed for day to day?
For anything too heavy or too bulky to roll: lifting complete points assemblies into place, work on bridges and retaining walls, loading rails and sleepers, and recovering derailed vehicles. Crane work often replaces days of manual labour with a few lifts.
Why is there an extra wagon attached to the crane?
In transport condition the jib is lowered and rests on a coupled jib support wagon. The wagon carries the end of the jib and holds it in travelling position. Anyone who only sees this state can easily mistake the consist for a normal freight train with an odd-looking wagon.
Is the Kirow crane self-propelled?
Railway slewing cranes are generally fitted with their own drive for short moves around the worksite. For longer transfers they're usually hauled as part of a train. Whether and how far a specific machine can move under its own power depends on the design - don't rely on blanket statements here.
Where am I most likely to see such a crane?
At larger construction projects involving points renewal or bridge work, and during transfer runs to the worksite. Because crane operations happen during possessions, you'll more often see the machine stabled than working - for example in an engineering siding or on a stabling track near a station.
Am I allowed to get close to the worksite to photograph it?
No. Worksite areas, tracks and operational railway installations are closed and must not be entered. With crane work, the added factor is that loads swing and the danger zone extends well beyond the machine itself. Observe from bridges, platforms or public paths.
How do I tell a railway crane apart from a road-rail excavator?
By the undercarriage and the size. A road-rail excavator is a road excavator with retractable rail wheelsets and sits on rubber tyres when the rail wheelsets are raised. A railway slewing crane has a pure rail undercarriage with buffers and a drawhook - it can't run on the road at all.
