To go along with the CNJ Blue Comet RPO car mentioned below, MTH has now released a two-car add-on set which contains a baggage care and a coach. I was pleasantly surprised to find that the coach includes people preinstalled so that I don't have to add them. The two cars have the same enhanced features that were found on the RPO car. I've done a mini-review that can be found on my Train Reviews page. Here are photos of the two cars.
