If you are planning on watching Coventry City at Doncaster Rovers on Saturday April 23rd, there are a number of trains that you can catch.
From Coventry & Warwickshire, it is easier to get to Birmingham New Street and then get the 10.30 or 11.30 trains to Doncaster.
Coming back, you can catch the 17.49 which requires changing at Sheffield as does the 18.18.
Doncaster railway station is approximately 2 miles from the Keepmoat stadium.
There are buses from outside the station and taxis are available.
There is also a dedicated bus service from the Doncaster Interchange bus station which is another option and runs from approx 2 hours before kick off. It's the other side of the shopping centre. It runs every 10 minutes direct to the Stadium.
