Height of VD portals and Atlantic Av tunnel

Postby NIMBYkiller » Tue Oct 03, 2017 9:30 pm

I tried to find it in previous threads about the Atlantic Branch but no luck. I'm working on a personal fantasy idea and was curious, at the current eastern portal for VD yard, what is the height of the tunnel? Long story short, I'm trying to figure out if at a 2 percent grade there would be enough distance to dive from the existing eastern portal to the pass below the trackway of the new western portal. The distance is about 1400 ft, so that allows a 28 ft dive if I did my math right. From what I can see, the western portal sits lower than the eastern one as well. Does anyone know the ground level of both portals?
