The R-10/12/14's fans really do not anything in terms of coolness but just circulate the air at best and nothing more, that I will agree to (coming from myself as an R-10 fan, no pun intended). I personally thought that the R-27/30's has the best non-air conditioned axiflow fans for any NYC subway cars that I personally experienced.However, someone should point out that the Pittsburgh Railways' 1700-series PCC cars, built in 1948-49 by St. Louis Car Co., also had large subway-type axiflow fans and all of its passenger side windows were sealed. They did have a very large roof (almost like in a "hump" or semi-ogee design) that did a very thin and long vent opening on each side, as I recall. -William A. Padron ["47D Drake Shuttle"] |
