There are multiple ways to get railway maxspeed data (1) data with a compatible license (2) mapping maxspeed signs along the railway line either by walking/cycling along the line or by GPS/photo/video mapping by train (3) GPS logging at a train and assuming the train /always/ drives at the maximum permitted speed – a bad assumption because sometimes trains drive slower because they are not delayed, try to save energy or try have a slower freight or local train ahead of them. I do not know if there is a public available dataset with UK maxspeeds which has a compatible license. I suggest you to join OpenRailwayMap IRC this evening (UTC) and ask if someone knows a dataset like (1). irc.oftc.net #OpenRailwayMap In Germany we are only allowed to use (2) and (3).
