Texas State Railroad (USA)
Ride a steam train on the longest and thinnest state park in Texas! Originally built as a prison railway, the Texas State Railroad was re-opened in the 1970s as a working museum. In the last decade it has run up against problems with local partisan politics and those who wish to strangle the Texas state park system, and is currently operated as a franchise operation.
