Doncaster Station has 9 platforms there are numbered 1-8 and then platform 0. It is a very good place to train spot and is one of my favourite places to train spot if you stand at one end of the platform you can see almost of the trains that pass and stop in the station. There is a good vantage point from a multi-story car park and you can see the depot next to Doncaster Station which you cant see from the platform. You get a wide range of trains which pass through the station Grand Central, Hull Trains, LNER, TransPennine Express and Northern. Common classes are 180’s, 43’s, 91’s, 82’s and 142’s
