Re: Amtrak Gateway Tunnels

Looks like a lot if wasted space under that Genesis that could be used to "future-proof" the new tunnels and allow for higher bi-level equipment in the near future.

In particular, the cross passages that will be required mid-river are expected to be most costly and challenging as they involve ground freezing.

Re: LIRR Mainline Third Track Project

There will still be only two platforms at Mineola. For third track, yes. I’m asking whether or not that holds true in assessments of making OB into a shuttle — the new interlocking config at Mineola seems to beg that course of action. Below you can see the proposed track geometry for the connection...

Re: LIRR Mainline Third Track Project

If you compare the first image with the last, you can see how the alignments differ between the current Expansion Project project and the early 2000's Mainline Corridor Improvement Project. These images are similar in size and style and should make the comparisons between the two projects easier to ...

Re: LIRR Mainline Third Track Project

The design-build contractors had proposed an optimized alignment in their bid, which would simplify construction and reduce the amount of track that would need to be cut and thrown during construction. The optimized alignment would place the new track south of the existing two tracks for the majorit...
