So, I myself am a train nut and I live in Britain, so, I might aswell give an overview of our trains. First category: High Speed 1. Intercity 125/HST 125 These units are of capable speed of 148 MPH but only ever reach 125 on mainline routes, these locomotives are well known not only in the British rail network but all over the world. (Intercity swallow 125) Power Type: Diesel Electric Horsepower: 2250 HP p/ powerunit Speed record: 148 MPH Maximum operating speed: 125 MPH 2. Class 220 "Voyager" The class 220 "Voyager" is a less well known train in the UK and oftenly counted as one of the lower spec high speed units in the UK, and often to be complained about noisy engines and cramped interiors. Each engine: 750 HP (Underfloor train, meaning each carriage has its own engine unit) Power Type: Diesel Electric Maximum horsepower: 3000 HP Speed record: 125 MPH Maximum operating speeds: 125 MPH 3. Class 390 "Pendolino" One of the more higher spec units in the UK, Pendolino is a train only operated by Virgin, and built by Italian company Alstom.

Maximum operating speed: 125/148 MPH 5. Hitachi Class 800/801 The Hitachi Class 800 is a true masterpiece in development, with being the first operating in August 2017, these will be able to match the German ICE trains. Power Type: Half Electric half diesel, runs with a pantograph but can also run via a smaller diesel engine under the floor. Speed record: ? Maximum operating speed: 125-150 MPH 6. Intercity Class 225 With these being the electric versions of the Intercity 125, they are well known on the ECML but still one of the less well known trains in the UK, but also currently the fastest! Power type: Fully Electric via Pantograph Power: 6300 HP Maximum operating speed: 125 MPH Speed record: 168 MPH More to come, as my browser is glitching out and I don't want to lose what I've just been typing for 30 minutes.
