Maybe some day all the passenger train stations will have idiot-proof boarding, like the Metro in Toulouse France. The platform is walled off from the tracks and the doors open only when a train has stopped in exact alignment.
The old Seattle monorail has extendable walkways which butt up to the train, at the downtown station where one platform serves two tracks. (Somehow this reminds me of Lionel stock-car loading and unloading).
