"Trainz Classics #1 "Harlem Line Edition"
A prototypical representation of New York's Harlem Line.

Activities will consist of historically accurate commuter and departmental operations typical of those seen from the early 80s to the present day. Each session is designed to reflect the real-life atmosphere of the locality and the services. For the first time in Trainz, we take you there!"

I was unable to find anything further about this release, but I'm excited. I grew up right on the Harlem line, and I'm looking forward to operating Metro-North trains on my hometown line. I'm particularly interested in how well they capture the actual track plan and surrounding scenery.
