AtoB magazine [1] has a wealth of information about every train operating company and ferry service in the UK, plus advice about how to book your bike on a train and coach and tram restrictions. It also has information about taking a cycle to Europe. Seat61 [2] is also a great resource if you want to take your bicycle by train beyond the UK.
