Devin Porteus' Eastern Hills and Southern (Lehigh Division)
We fit a pretty good representation of the famous Lehigh Valley mainline from Lehighton to Wilkes-Barre along with a couple of branch lines into Devin's basement thanks to the space-saving properties of N scale. It was a trick to miss the Lally columns.
Scott Thompson's Effingham, IL
It was an unusual shape - 4x14' island, with a couple of columns smack in the middle. But I think we made it work. I found the town of Effingham, IL, which features a junction between Scott's favorite Penn Central and Illinois Central, along with one of the shortest short lines in the country which connects them.
