As well as the issue of legality, there is a question of whether travelling by train would be safe - while you may not relish a long car journey, I wonder if a long train journey (or series of journey legss) would be abnormally stressful, in terms of feeling out of control if you end up trapped in a queue or people crowding close to you or someone sitting down to close to you unexpectedly, at every station or interchange point.
Given that for most people the risk is as high as driving 185 miles, unless the OP is in a higher risk group, then this is unlikely.
