With around 30 different classes of DMU from the first generation that operated in the UK, there is a wealth of types that we are still to see in game. These DMUs came in a variety of different layouts from Low Density to Suburban to Intercity/Long Distance. The general design of many classes were almost identical except for a few features such as buffet cars and corridor coaches. There were a small number of the types that featured hydraulic transmission as opposed to the more common mechanical transmission. Engines were from manufacturers such as BUT, Leyland and Rolls Royce in the most part. I think it would be fantastic to see more of the classes in game, particularly the examples that no longer exist. To achieve this, I recommend the website https://www.google.co.uk/url?sa=t&s...AQFnoECCoQAg&usg=AOvVaw0HYkjTzsG907gf5uf-IiaG There is a treasure trove of data within that could potentially make some of the extinct classes a plausible reality. As far as routes are concerned, they would work well in many as these types were once seen the length and breadth of the network. Thanks for reading.
