Oh! The TH2100 has a 4 speed? I've never heard a rail vehicle shifting gears before. Very cool!! Thank you for the great vid!! The Tenryu Hamanako Line is quite scenic. Regards!!

These are by no means the only trains with gears; even modern DMU's with hydraulic transmissions have two "gears", the first stage being driven through a torque converter from standing until a certain speed is reached, after which direct drive from the engine is automatically engaged.. British Railways also built numerous types of DMMU's in the 1950's &1960's that had manually selected 4-speed epicyclic gearboxes, some of which lasted until the early 1990's, which I used to drive where I worked in South Wales before they were all scrapped. Many were originally 3-car units, two of which were power cars with a driving cab & 2x150hp diesel engines per power car with a 25 ton trailer car sandwiched between them... By the 1990's, the (middle) trailer cars had all been removed leaving just the two power cars coupled together, so the acceration rate on them was reasonably smart. There were some built as two-car units that had a driving trailer car and one power car with a driving cab that only had 2x150 hp engines... these were strictly reserved for services that didn't have to climb steep gradients, unless coupled to another unit that had 4 engines...Most of these units had large windows behind the driver's cab, so that that passengers could see what the driver saw as the train progressed... No other trains have been built with this feature since... I am now very happily retired after 40 years service, but these videos still fascinate me, there being so many similarities (apart from the track gauge) to railways in the UK...
