For those of you who donít know the history, the change in fan design was the result of passenger input. Sometime circa 1965, the TA equipped 4 R-27/30s each with a different design of fan. 2 of the cars had conventional axiflow fans set at various speeds and 2 had axiflow fans with a flat baffle with holes at various places along the edge. The cars for put on display for a couple of weeks on the seldom used B3 exp tk at 34/6, and passengers were invited to enter the cars, check out the comfort level of the different cars and vote on which ventilation system they preferred. The design which won out was the design with the baffle which as installed as original equipment became what was installed on the last of the R-32s, the 38s and the non A/C R-40s.
