I had the first version with the matching cars. If I recall correctly there was quite a delay in getting the pass cars made. As others have pointed out, the engine could barely get moving with the 4 pass cars. Always thought the pass cars really were not really a great match for the engine, as the ends of the pass cars just didn't give the train a continuous look. Wound up selling the set for pretty much what I paid for it.
One thing I noticed about the Phantom loco, Wonder if the inspiration for the red cab windows came from Neil Young's tour bus ?
