On the last day, we also visited the Federal Railroad Administration (FRA) and the equipment in this room was a simulation for the engineer's control room in a train. Great thanks to Mike and Chris' facilitation. Now we all had some experience driving a train.
This visit was especially meaningful to me because I visited a railroad dispatcher center in February and learned how dispatchers interact with different parties, including conductors, PTC, line up signals for engineers, etc. This time I saw the effect of dispatchers' work from an train engineer's perspective. Now I can better connect dispatchers' work model and engineer's work model.
