I'm sure you have heard about the latest bullet train in France that will do 350mph.
In the 1970's the Russians experimented with their own bullet trains.
This one was powered by two engines from the Yak-40. It could do a max speed of 180mph
The Russians also put jet engines from a TU-134 on a passenger ferry, enabling it to do 60mph on the water.
Sadly, none are in use these days.
