These locomotives were constructed in 1908 for the Lacroze Rural Tramway / Buenos Aires Central Railway in Argentina. They were designed with a central cab as was common at the time for electric locomotives of this size. The locomotives used a trolley pole for current collection (500v DC overhead). They were able to travel at up to 20 mp/h and could maintain maximum output for an hour.

The F Stock was built for the District Railway in the early 1920s to increase capacity and to replace deteriorating B Stock [1], the construction was partly funded by the government to help British industry transition back to civil manufacture. The F Stock was built at a factory that had built armoured vehicles in the war, that and their steel construction may be why they gained the nickname of "tanks"!

The F Stock was more powerful than earlier District Line stock which gave them a superior performance. Despite their high passenger capacity they were unpopular due to their interior appearance. This was improved in service. The F Stock had non-standard control equipment and thus could not work with other District Railway stock.
The F Stock was transferred to the Metropolitan Line in the 1950s. They were fitted with air operated doors and other enhancements including windscreen wipers [2] to the distinctive (though troublesome) oval windows. The F Stock was finally withdrawn in 1963 after replacement by A Stock. None have been preserved.

The Class 350, part of the Siemens Desiro family of electric multiple unit, was built in three batches since 2004 and is operated by London Northwestern (LNWR). The Class 350 is the mainstay of LNWR intercity regional services. The Class 350 has also served, in the past, with London Midland, Central Trains, Silverlink, Southern and First TransPennine Express.

The Class 350 is capable of up to 110mp/h (except the 350/2) and collects its power from the 25kV AC overhead wires though some (350/1) can use the 750v DC third rail too. However, these days only operate as AC EMUs. They are part of the Desiro family which also includes the very similar Classes 185, 360, 444 and 450. Indeed the original batch of 350s was originally ordered as Class 450s [1].
London Northwestern Railway use the 350/1, 350/2 (which has high density seating), 350/4 and the more recently built 350/3 on services down the West Coast Main Line to London Euston as well as some local services in the West Midlands. Some are to be replaced by Class 730s.
