I think it is about time we get a full NEC. Track from DC to Philly is flat, rest of the corridor will have more gradual inclines and declines. Yards/sidings/ will be finished after the main track is complete. Right now I'm stuck on the beast that is Philadelphia. Brain turns into scrambled eggs every time I look at the track. I'll do my best and post updates every few weeks.
Take a gander
