SIRT Track

I am interested in learning more about how the Staten Island SIRT trackage is configured. If someone is familiar with the line and is willing to discuss please email or PM me. Unfortunately I don't live close enough to check it out myself. I'm particularly interested in the track south of the Expressway.

Thanks in advance,

what do you mean by configured? it's a two track line with top-contact third rail if that's what your looking for.

There are 2 track universal interlockings about every 4 stations or so.
