Train Wreck: Stay out of first cars

Most commuter trains today work in push mode
That means the locomotive is very often behind pushing the cars so the train is like it is moving backwards. Riding in the first car or two on a train in "push mode" is not a good idea. The passenger car is like a hollow tube and if the train runs into anything, like another train with a locomotive on the front, the riders of the train are at a severe disadvantage.
