From NMRA Website:

The L & K railroad links Baltimore and Pittsburgh. The Baltimore and Ohio station and yards in Baltimore has replicated downtown Baltimore. The Pennsylvania Railroad is featured in Pittsburgh with traffic from both railroads traveling across the L & K mainline. All locomotives are equipped with sound. You have to see the excellent workmanship, super scenery with unbelievable detail. This layout appeared in Internet Trains, NMRA Calendar (2011), Walthers HO catalog and MR Trackside photos 3 times. George, was also the cover and feature article in the August 2012 issue of NMRA. See a video of his layout on YouTube: http://youtu.be/UnSLOLchjsk
