Orange/Red Compatibility

Postby Mdlbigcat » Mon Dec 13, 2004 7:31 pm

Can Orange Line cars run on the Red Line and vice versa? They look like they are roughly the same size and width give or take a few inches.

Also how come there are no track connections between the subway lines? Even if the passenger carrying equipment cannot run between the lines, at least work equipment could run on them like it's done in NYC.

Not really, since the 01200s would be a bit too low for the Red Line Platfourms, and vice versa with the Red cars in Orange Stations, plus the length and width of those cars would make the Red Line cars practically impossible to run on the Orange Line's narrow right of ways.

The Red Line cars are 70 feet in length, 122 inches wide while the Orange Liners are 65 feet long and 111 inches wide. And as for the track connections, none were put because of the uniqueness between the three rapid transit lines.

Orange Line cars are 65' long and 9' 3" wide. Red Line cars are both longer (69' 6") and wider (10' or 10' 2" wide). Floor height from top of rail is a bit different too (4' 1" on the Red Line... can't find what it is for the Orange Line at the moment).

So... close, but no cigar. Remember that the Orange Line was initially built as an elevated line, and necessitated smaller, shorter, lighter cars than the Red Line, which was built from the start as a heavy rapid transit subway line.

I have the Orange Line (at least the 01100s) at 3'-8 11/16" for floor height. Should be the same today. The Blue Line, incidentally, is listed on the 0500s as 3'-5 1/2", and of course that line was originally for streetcars operating through the tunnel under the harbor, meaning even smaller overall clearances.

It was interesting recently when I compared closely the dimensions of the Red Line 01400s and the Orange Line 01100s. While they appeared about the same except for length, there were actually a number of other dimensional differences and variations. I imagine the same is true with the Hawker-Siddely 01200s and 0600s. That's Boston for you - no two are exactly the same!

Tha Orange Line has IRT-like dimensions, while tha Red Line has IND/BMT-like dimensions.

Also, the Blue Line has IRT dimensions, their cars are only 48 feet long, and theur tunnels have a very narrow clearance like many A division IRT lines.

I believe that back in the 80s, the T considered modifying the 01100s to run on the Red line, but was given up due to cost.

Also, back in the early 80's, the T was going to sell off most of the 01100's to SEPTA to replace the old Broad St cars [and hold them until the Kawasaki cars arrived], but a strike at Hawker-Siddely delayed the delivery of the 01200's by about a year.
