Thank you, David, for the link to the CZ website - it has an amazing wealth of information.
This set seems destined to become one of the collectible classics of the hobby. I appreciate the way Atlas O is offering this set. The four car sets provide a number of options and make a really nice way to get a smaller train that still captures the look and feel of the whole trains. I don't model the roads over which the CZ ran, but the PRR Silver Rapids sleeper gives me an opening to go for this train.
