According to the program guide, today’s Trains & Locomotive episode on the RFD-TV channel will be “Big Boys and Challengers” featuring classic footage of some of the largest steam locomotives ever built. This is a repeat of an episode that aired in 2014 but it should be worth watching again. Be advised that the show is now on from 5:30 to 6:30 PM, eastern time, which is 30 minutes earlier than it used to air. It’s on at the same time everywhere in the US so that would be 4:30 in the Central time zone, etc. So set your DVR's if you're not able to watch it live.
RFD-TV is channel 345 on Direct TV and channel 231 on the Dish Network. Your local cable channel may or may not carry RFD-TV.
RFD-TV also carries a 30-minute show called “I Love Toy Trains” which features mostly 3-rail O gauge layouts. It’s on Thursdays at 4:00 PM eastern.
