Question

I have a train ticket that has been issued to me, next to the price of ticket is a W what does the W mean?

Answer 1

W = paid by Warrant

Answer 2

Paid by warrant, usually by a private company or government department. If you handed the ticket in for a refund you would not be given cash, but a credit to a warrant account.
