I really wanted the camera cars and/or engines for modular shows. People love to see the monitor with the train's eye view of the track. Whenever it's running, there are a few people watching on the monitor. Next step is to put one of the wireless cameras in a tall freight car load and have it look over the train for a different perspective.
For the recorded engineer's view that George is looking for, the flatcar mounted camera will probably do the trick.
