I found this while searching around the internet. It's probably not a program that many people on this forum would pursue but I thought I'd pass it along since I had never heard about it before. Certificate in Railway Studies by Distance Learning offered by the University of York and the National Railway Museum. http://www.york.ac.uk/inst/irs/irshome/academic/leaflet_railway_studies_hist.htm It's a graduate level certificate that takes 2 years to complete. The cost per year is 1100 pounds for UK/EU residents and 3170 pounds for all other students. (Roughly $4400 as of today.) They also offer a Certificate in Transport History. http://www.york.ac.uk/inst/irs/irshome/academic/leaflet_transport_hist.htm
The National Railroad Museum in York, UK, is a great place to visit - I've been there several times. http://www.nrm.org.uk/home/home.asp
Kansas City has a fantastically restored train depot. I attended EDI (Economic Development Inst.) and it was one of the highlights of the trip. http://en.wikipedia.org/wiki/Kansas_City_(Amtrak_station)
