Also, I wonder if the NYCTA's IND/BMT R44 and R46 cars have something foreign in the left side, since they never built a window to the side of the cab door of both cars. They should have done it, just place two sets of glass windows, in the "brown-wood" are of the passenger cabin to enable passengers to peer into the "cab storm door" of both R44/R46 cars.
The left side of the R44/46 [as well as the R40/40m/42/62/68 cars] contains the mechanisms for the route number/letter signs. Therefore no need for a window to be built in the interior of the car on the sides.
For history's sake, the earliest R series [R1, 4, 7, 7a] had left-side windows, but they were covered up. Starting with the R10, there were no left side window, just the window for the motorman.
Despite the full-width cabs, WMATA, MdMTA, CTA, SEPTA Broad St Subway, Cleveland RTA, and LACMTA have the left-side window to see out of their heavy rail cars, and peek into the motorman's area.
Of course if you ride PATH, PATCO, and SEPTA MFSE cars you have the luxury of sitting in a bona-fide railfan seat.
