Kreisbahn Mansfelder Land GmbH (KML)

Updated: August 2026 – Most questions in railway matters ask “who’s running that?”. For municipal railways, the second question is at least as interesting: “who actually owns the track?” The Kreisbahn Mansfelder Land GmbH (KML) stands for companies where the two answers can pull apart. This page explains what follows from that – for operations and for your sightings.

What is the Kreisbahn Mansfelder Land?

The Kreisbahn Mansfelder Land GmbH, or KML for short, is a railway company with a municipal background in the Mansfelder Land in Saxony-Anhalt. The name alone gives you three solid pieces of information: “Kreisbahn” points to a tradition of municipal ownership, “Mansfelder Land” names the area, and “GmbH” gives the legal form.

What the name doesn’t tell you is the way it actually operates. Municipal railways can run trains, maintain track, or do both – and that split changes over the years more often than you’d think. This page therefore deals with the pattern and leaves the snapshot to your own observation.

For how to place railway companies in general, see the guide Who’s actually running that? Identifying railway operators.

When the railway owns the track

The most interesting part of such companies is the part you can’t photograph. Whoever operates railway lines carries responsibility for their condition, safety and availability: track bed, points, level crossings, signalling equipment, vegetation along the line, winter maintenance. This work has to be done whether a train runs there daily or once a week.

That produces a calculation that shapes many small networks: the costs are tied to the line, the income to the trains running on it. The less that runs, the more each kilometre of track weighs. That’s exactly why it matters to such operators that their network gets used – including by other companies.

Network access at small infrastructure managers

So that the owner of a track cannot alone decide who is allowed to run on it, access to railway infrastructure is regulated. Operators publish the conditions and charges under which their network can be used. There are simplifications for very small networks, but the basic principle of open access still applies. Companies of this kind count among the non-federal railways whose interests are represented by the Netzwerk Privatbahnen. A comparable operation in neighbouring Saxony is Regio Infra Service Sachsen, which maintains track without running passenger trains itself.

Aspect	What the operator sets	What that means in the field
Terms of use	the rules under which trains may run	other companies can turn up regularly
Charges	what using the network costs	explains why small networks depend on utilisation
Capacity	when which trains can run	trains often fall into fixed time windows
Maintenance	condition of track and equipment	temporary closures with no obvious cause
Operations management	who runs and secures the operation	staff on site even without visible train traffic
Third-party connections	linking businesses to the network	transfer points and siding along the line

The first row matters most for sightings. It explains a situation that puzzles many people at first: a train runs on a Kreisbahn line carrying a completely different name. That’s not a contradiction – it’s the normal case for an open network.

Why small networks are hard to observe

Whoever stands at a main line waits for the next train. Whoever stands at a small network may end up waiting for the next day. That’s not down to a lack of importance, but to how the operation works: trains run when there’s demand, and demand comes from the schedules of the connected businesses.

A few practical rules follow from that. Weekdays beat weekends, because traffic follows shift patterns. Mid-morning and late afternoon see more movements than midday. The state of the track tells you more than the timetable – bright, freshly worn rail heads at a set of points mean a train has run there recently, even if nothing is happening right now.

Also useful: sidings and transfer points along the line are good clues as to where any traffic originates at all. Where loading facilities, silos or sheds sit right next to the track, there’s a reason for trains to run. Where the line only passes through open country, it’s a through route – and there you’ll wait longer.

And finally: note visits that turn up nothing too. Over months, that builds a picture of which days and times actually see traffic at all. For small networks, that’s often the only statistic available.

Recognising it in the field

Typical vehicles on such networks include diesel locomotives such as the East German V 100, shunting and transfer machines of the Class 295, or industrial types such as the MaK G 1206. They share the same requirement: robust, available second-hand, usable for a long time.

Comparable companies can be found at Kreisbahn Aurich, the Anhaltinisch-Brandenburgische Eisenbahngesellschaft and the Leipziger Eisenbahnverkehrsgesellschaft.

Sightings on small networks

On a small network, every observation is a bigger share of the overall picture than on a main line. That makes it all the more important to record it properly.

For how to build this into a collection you can still use years later, see the guide to keeping a sightings log.

Common mix-ups

Verdict

The Kreisbahn Mansfelder Land GmbH stands for a dual role that’s widespread in German railways yet not well known: whoever owns a track isn’t just running trains on it, but also managing a right of way that others are entitled to use. Keeping that in mind means asking the right two questions when you’re observing – who’s running here, and on whose track.
