One of the same Nina trains as above, but photographed at a time when it was still carrying the colours of MO, but had already the stickers of TMR on its sides.

In 2003 not yet all the train services on the old MO line could yet be run with modern Nina trains. This is a steering cab coach Bt 33 from the year 1965 and behind it is the motorwagon ABDe 4/4 also from the year 1965. Note that in front of the door there are logos of both MO (the blue one) and of TMR on top of each other.

This BCFe 4/4 no.1 was the very first train of the train company MO. This picture has been taken on 22.4.1911. It's unknown who took the picture. According to the Swiss law it is now a public domain picture as it has been published more than 70 years ago. It was published at the Schweizerische Bauzeitung, Band 57, Heft 16. Source: Wikipedia.

At that time the MO railroad used 8000 V 15 Hz AC. The whole railroad was converted to the standard electric system of SBB in 1949. MO had altogether four of these trains, all built in 1910. They were all rebuilt for 15kV AC in 1949.

This ABDe 4/4 no.5 was the second generation of MO's trains. It was built in 1955 to supplement the very old four first trains. This one remained in working order and served as a reserve until 2002, when it was sold to the railway museum Bahnmuseum Kallnach.

A detailed view of the ABDe 4/4 no.5. Note the old logo of MO. At the side of the train it is listed as BDe 4/4 and not ABDe. This is because at that time they felt the old first class was no longer worth to be designated as first class and should be part of second class.

Still one more view of the ABDe 4/4 no.5. This shows clearly the transportation needs of the MO railway in the 1950s. Only half of the motorwagon is for passengers, the other half was for cargo. And it was typical of the time that this motorwagon had one or more wooden cargo coaches attached as there was an alumnium factory in Orsières which created a need to transport a lot of goods. Road transportation in those mountaineous slopes was not too easy by that time.

This was then the third generation of MO's trains. This is one of the so called EAV trains. The EAV train was a standardised train type with one motor wagon ABDe 4/4 plus one steering cab coach Bt. This was a common type and much used by many private railways in Switzerland, for example Südostbahn, Mittelthurgaubahn etc. These trains were built in 1965. Here we see one of them ready to leave towards Orsières from Martigny in 2001. Note the new painting.

A close look at the EAV type motorwagon ABDe 4/4 no.6 from 1965. MO / TMR had five of these EAV trains. One of them was bought used from RVT, Region Val de Travers. Two EAV trains probably still now remain in working order at Region Alps. Nowadays these EAV trains are known by their new type designation ABDe 537, numbers 506–.

The MC, Martigny-Châtelard railroad is already well over 100 years old. It begins in the city of Martigny as a metre gauge line, which first runs as an adhesion railway, but then at its steepest points uses a system Strub cog wheel third rail drive system. The railway is electrified with 850 V DC. Using the rack rail system it climbs up at up to 20% incline. The line is only 19 km long, but yet it takes close to an hour for a train to climb up. Originally the railroad was founded as Chemin de fer de Martigny–Châtelard, but today it extends beyond Châtelard over the Swiss-French border and connects with the French Saint-Gervais–Vallorcine railway. The Saint-Gervais–Vallorcine line is also metre gauge, but it doesn't use an overhead catenary, but a third side rail for collecting electric current. These trains are equipped with both overhead DC electricity systems as well as side rail electricity systems, so that the same train can ride through, starting from the former MC track down at Martigny and then running through Châtelard on to Chamonix and beyond. This through running service is now marketed under the brand name of Mont-Blanc-Express. The same name is used also for marketing the former MO line and bus routes over the Alps to Italy.

This is the Mont-Blanc-Express. It is of the type Z800 built by the Swiss company Stadler. It was bought together with the French SNCF which needed similar trains for their Saint-Gervais–Vallorcine railway. This was the first type that could run both on the MC route and the SNCF route.

This is how the trains of MC, Martigny-Châtelard, used to look like before the merger to form TMR. This is the steering cab coach BDt 68. It was typically kept together with one of the motor wagons of the type BDeh 4/4, which were from the years 1957 and 1964. Later, after a refit, these motorwagons were called ABFeh 4/4 (= first and second class plus freight).

These are the current trains running on the former MC line. This is today TMR's Beh 4/8 n.72, built as Stadler's type Stadler Spatz. TMR has two of them for the service from Martigny up. They were built in 2011. These are almost identical with the newest SNCF trains running now on the Saint-Gervais–Vallorcine railway.
