Why R-44's on SIRT?

[railfan365]

Does anyone have any idea why the R-44's on SIR are continuing in service while the ones on the 8th Avenue have all been retired due to structural defects? After all, they were all purchased together.

The operating conditions on the mainline are much more rough than the ones on the SIR line. In addition, the cars on the mainline have racked more mileage than the cars on the SIR. But it's not much of a difference once you consider that the SIR cars only have a maximum of 5 years left anyway....

The SIR cars had no replacements on order, the mainline 44s were scraped in time to be replaced by the 160s, which is why the remaining 32s and 42s got a reperive.

the SIRT R44 cars have all recently been remodeled on the interior, new seating, fixed damaged interior fittings, cabs have been cleaned up cosmetically, silverpaint on the outside of the cabs, heavy cleaning of the floors and walls, some cars even received new linoleum flooring (black, instead of the usual brown/tan) also all of the original M logos have been replaced with the modern MTA Staten Island Railway logos

The recent overhaul on the SI R44s is expected to extend their lives by several more years, until replacement cars are available.

Plan A is to ship the R46s to SI, replaced in the subway by the R211s in or around 2015. The R179 will mostly be to just phase out the 300 or so R32s and R42s left.

Once the R46s are in SI, would they be converted to single units (as the R44s are) or remain as is?

would anything special modifications be needed to the R46s so that they can run on the SIR to comply with FRA requirements, (the R44's here are modified with a heavier frame, different trucks, FRA safety glass etc...)

Externally, the most notable feature on the SI R44s are the FRA standard grab irons.

R-36: I believe both the R-44's and 46's were built as cab-cars and cab-less cars. If that makes them "single" units, that's fine. But, I think both were the same set-up.

Some cars having cabs and others not does not make them single units - it makes them A units and B units. A single unit is a car that is not permanently attached to any others.

The 46s would be converted as nessisary, however, I have not heard anything about them reverting to signle units.

to settle the discussion. the R44s and R46s were built as single units and converted into permintate units during thier rebuilds. The B cars have always been B cars, and required an A car to operate.

I think you may be confused with the R62/R62A/R68/R68As, which were originally all single units and converted into linked unit sets during SMS.

The SI R44s are single units as they can operate independently (A units), unlike the linked A-B-B-A R44/46s.

No, I'm not confused, I'm correct. they were all delivered as singles and the subway's cars were connected, during rebuild, not SMS, that came later. NYCsubway.org has a chart with the orignal 3 digit numbers for both models.

MUE-2s are a diffrent story.

Aren't there also B-unit SI R44s? I know that all of SI's R44s have couplers.
