Bière–Apples–Morges railway BAM is a metre gauge small railway which is owned by the organisation Transports de la région Morges-Bière-Cossonay MBC. Both acronyms BAM and MBC are often used to refer to the railway, but lately most often MBC. It is a metre gauge railway, roughly 30 kilometres long, beginning in Morges by the federal "big" railway, by the lakeside of Lake Geneva. The line is electrified with 15 kV 16,7 Hz AC just like the federal railways. One speciality of the railway is that it serves a large area of army barracks. Military trains carrying tanks and other heavy army equipment is often transported and this is done with adapter bogies so that normal gauge wagons can be hauled all the way to the army barracks near Bière. Passenger traffic is quite frequent.

This motor wagon Be 4/4 no.11 is from the year 1981. Today it's mostly just used as a reserve as newer wagons also exist.

The same train Be 4/4 no.12 in Bière in 2023. These motorwagons are nowadays rarely anymore used for passenger traffic, but they act as locomotives bringing normal gauge cargo wagons using so called roll cars or roll bogies on the narrow gauge track to Bière and back. Note how the logo and the paintings have only slightly changed in 20 years.

Since 2017 most of the passenger traffic on the line has been run with these Stadler-made new trains of the type ABe 8/12 which the railroad has named "Le Joran". Trains are now branded as trains of "MBC" and not anymore "BAM". MBC stands for Transports de la région Morges-Bière-Cossonay.

One of the new Stadler ABe 8/12 trains waiting at the station of Bière as a regional train to Morges. At Bière there's a large Swiss army garrison and just moments after this photo was taken, there was a crowd of soldiers with their equipment and even assault rifles with them waiting eagerly to board the train and get to a home holiday using first this train and then apparently SBB's long distance trains from Morges onwards.

The same train as shown above, but now seen from its other end. Note that the train has two motorised wagons and both of them keep their both pantographs up as the driver knows there's going to be a heavy load this time.

Still the same train as shown above. The different sides of the motorwagons are taped in different ways. On this side station names of the MBC network are shown.

MBC uses its new Stadler motorwagons also like this on less frequented routes. A full new ABe 8/12 Stadler train consists of two motorwagons plus one unmotorised low-floor coach in between as shown above. But here MBC uses just one of the motorwagons without the other motorwagon and without the middle coach. There's an old driving trailer wagon at the other end. These two wagons are quite enough to carry the few passengers, and while the new motorwagon has one pair of doors which is reachable low-floor, this also fullfills the accessibility requirements of the new Swiss law.

This was the other end of the same regional train as shown above. This is a driving trailer or steering cab coach wagon Bt 51 built in the nineteen eighties.

MBC's Tm 2/2 no.41 is a narrow gauge rail truck which is used in various track reparation works and also for fixing the catenary wires.

In addition to the metre gauge trains, MBC has also this one normal gauge line locomotive, a former SBB Re 420 no.506. It is mainly used with military trains.

MBC has also one old normal gauge electric shunter locomotive of the type Tm III. It is used at Morges station whenever there is a need to move cargo wagons between the metre gauge network of MBC and the normal gauge network of SBB. Typically this means moving normal gauge military transport vehicles being moved on adapter bogies so that they can roll on the metre gauge rails.

Adapter bogies, also called as roll bogies or roll cars. When a normal gauge wagon is put on top of these, it can roll on metre gauge rails.

MBC is not only a train company. They also have a large network of bus lines.
