Sorry Dave, the Westinghouse pump was for air brakes, not the usual vacuum. IOW Rly was one of the few pre 60's services to have them. They had the one-pipe system, BR eventually opted for the 2-pipe system which was faster acting on longer trains (usually freight) but even so, the 1-pipe system was a lot more efficient than vacuum. Continental rlys had air braking for yonks before BR decided they had better spend some money on improving things. |
