This picture was taken in 1938, and shows two streamlined locomotives. What a site these trains must have been, if you were used to the old style locomotives.
One of the problems with train travel is that the trains start and stop too much, and you lose about 30 minutes every time the train stops. I think they should go to a system where there is one train car (motorized) at a station that people get on. When the real train goes by, the one car train starts up, catches the main train, connects to it, and then the people on the one car train transfer to the main train. Then the little one disconnects and goes back to the station. Would work the same way in reverse when someone wants to get off. This way, the main train could travel non-stop, and still people could get on and off at each station. No one listens to me though.
