Re: Expansion of single track Empire Connection to double track?

Considering that the North River lines dive at 2% in the 1500'west to 11th Ave, such an Empire line addition would have to be around 4% in the 1800' from 9th to 11th, that's steep. I'm guessing that the existing Empire line is relatively level and the WSY lead rises.

Here's a PRR profile from the 1910l ASCE papers. Find 11-10-9th at the right. The horizontal lines are 10' vertical spacing, you'd need 20'. WSY's roadbed is roughly on the original street surface. The Empire line would be in that "Sand Gavel & Loam" space.

For the 7 line, I think it's under Hudson Blvd. The profile suggests it would have to be under the North River line. So, sorry but I think you're running out of options here.
