It seems close enough for them to use it anyways.
7 minute run.

Not ideal, sadly. I suggested it because, as I said, they were using CNG buses anyways.
This brings me to a question: with CNG being cheaper and (a tiny bit) cleaner, why haven't all depots undergoing rebuilds (such as FR, prior to Sandy) been equipped to handle CNG filling? I don't want to get into the pro/con argument of NG extraction, but it's going full steam ahead anyways, might as well take advantage of the low prices and slightly better emissions.
