I found this video on YouTube. While the entire video is worth watching, there are two especially interesting segments.
First at the 6:25 minute point, there is a train with 10 engines and 13 cars. There is a prototype for everything we do with model trains! I suspect that this is a power balancing move.
Second at the 25 minute point, a Schnable car is carrying a decommissioned nuclear reactor. This is the first time I have seen this type of car in use anywhere. I thought it is interesting that a rail truck leads this train and that the train has several cabooses. NH Joe
