This is a class D1M diesel multiple unit of the Romanian state railways Căile Ferate Române, CFR. The original D1 was an old diesel multiple unit built by Ganz-Mavag in Hungary in the 1960s to the 1980s and they were quite common throughout the former Soviet Union and also throughout much of the former eastern bloc countries. This one is a thoroughly rebuilt D1, now called D1M (M for modernised). In 2012 Moldovan Railways and the company Electroputere VFU of Romania started a thorough rebuilding program for these old trains and this is the result. It has for example received totally new Volvo Penta ship's engines.

For comparison: This is the original D1 train of Ganz-Mavag in its original Soviet Russian painting. Quite a change if you compare this with the modernised one above.

One more of Romanian state railways CFR's class 41 electric locomotives, but this one is in a very desolate and rusty state, although it's still in use. Not even the normal lamps are functioning any more, but someone has screwed temporary lamps onto it very low down.

Romanian state railways class 60 locomotive, originally class 060-A. It is a diesel-electric six axle locomotive built by Electroputere Craiova, but it is based on a Swiss design of the companies SLM Winterthur, BBC and Sulzer and that is the reason why it quite a lot resembles the Swiss federal railways SBB's electric locomotive class Ae 6/6. They were built during a long period, 1959 to 1981.

Same train as in the picture above. These old double decker coaches are the same that used to be common in former East Germany (DDR) in regional traffic for example in the area of Leipzig. Nowadays these have long since been scrapped in Germany. They were built by Waggonbau Görlitz in the DDR.

This is another class 60 diesel locomotive, but this one is owned by Deutsche Bahn's daughter company DB Schenker Rail Romania. Picture from Videle 15.8.2019 by Markku Salo.

This is a class 64, six axle dieselelectric machine, which is a rebuilt and remotorised class 60 locomotive. See above for the original class 60. Now these class 64 machines have an EMD turbocharged V8 engine of the type 8-710G. It has a power rating of 1582 kW and a max speed of 100 km/h. the modernisations from class 60 to class 64 have been made since 2004.

This is an old class 80 dieselhydraulic shunter engine of the Romanian state railways CFR, now working for their passenger services division CFR Călători. These machines were built by Faur 1966 to 1985 and many of them have already been modernised and remotorised - but this one not. This is a 920 kW machine with a top speed of 100 km/h. They are used for shunting but also for light line traffic.

These are old French SNCF series X4500 trains, bought used to Regiotrans in Romania. There are now five private passenger train operators in Romania and Regiotrans is one of them.
Picture from Brasov 19.9.2010 by Markku Salo.

Regio Calatori is one of the many private rail operators in Romania now. This class 57/97 trains are former French state railways SNCF's class X4500 railbuses. The X4500 model dates back to the years 1963 to 1970 and some of them were rebuilt/modernised in France since 1980. This is one of those rebuilt units.
Picture from Brasov 4.5.2018 by Marek Graff.

Also this Regio Calatori class 57/97 railbus is one of the former French SNCF X4500 railbuses, but this one has not been rebuilt and modernised. It still looks as it used to look like in France in the 1960s.
Picture from Brasov 4.5.2018 by Marek Graff.

Yet another one of the Regio Calatori's class 57/97 railbuses, former SNCF X4500. This one has not been modernised, but at least it has been freshly repainted.
Picture from Brasov 4.5.2018 by Marek Graff.

Still one more of Regio Calatori's class 57, former French SNCF X4500 railbuses without any modernisation, just like they used to be in France in the 1960s.

One of the private or open access cargo operators in Romania is the German DB, Deutsche Bahn as DB Cargo Romania. They started by importing locomotives from Germany, Denmark and from the UK, but now they have even newer machines in use in Romania. This one is a DB class 480. The type is called Transmontana. It is an 8200 kW strong and 160 km/h fast six axle machine built by the company Softronic and it is the newest locomotive type in the country. Transmontanas come with two distinctly different locomotive fronts. DB has 19 of them in Romania.

These two machines are former British Rail class 92 machines. They were built for traffic in the Channel tunnel and therefore they can operate either from 25 kV overhead catenary or from a 750V DC side rail. Many of these machines became superfluous in the Channel tunnel traffic and some of them ended up at DB. DB took them to Romania and used them there for several years. But now they have been pushed out of use also in Romania and superceded by Transmontana locomotives shown above. These two machines still show DB's paintings and registration details as DB Cargo Romania, but in fact at the time this photograph was taken, these two were already owned by a private Russian company. They had been in tests in Croatia and the intention is to start using them in coal trains between the Croatian-Hungarian border and the harbour of Bakar on behalf of the company Transagent Špedicija. Built by ABB and Brush Traction in the early/mid ’90s, British Rail Class 92 was originally designed to operate trains between Britain and France through the Channel tunnel. With a total of 46 units, the fleet is capable of achieving а maximum power of 5 MW on overhead 25 kV AC or 4 MW on third rail 750 V DC. Apart from the ones sent to Romania, DB Cargo also uses such locomotives in Bulgaria, where they are still wearing the original EWS livery. (Source: railcolornews.com)

This locomotive is marked as belonging to Train Hungary and it is photographed here in Hungary, but it is a Romanian class 40 machine registered in Romania. Class 40 machines were made by Elektroputere 1965-91. It's a six axle 5100 kW machine with a top speed of 120 km/h. It is an older version of the class 41 pictured higher up on this page. Train Hungary is a private cargo operator, which operates not only in Hungary but also in Croatia. All their locomotives are of Romanian origin.

A CFR class 150 steam engine has been placed onto a stand as a monument at the station of Brasov. It's a wartime German Br50 machine.
Picture from Brasov 4.5.2018 by Marek Graff.

Another steam locomotive also marked as CFR class 150 is kept as a monument at the station of Galati. Both this one and the machine in the picture above are marked as class 150, but they are not identical. This one is a German Br42 war locomotive, "Kriegslok" left behind by the German army during World War two. The locomotive at Brasov is also German, but it is of the German DRG class Br50 captured to Romania at the end of the war.
