[edit]Speed of turbines on the 6-8-6 There was a query about and alteration to article re; the speed of turbines rotating at 2,000 m.p.h. or 2,000 r.p.m. Verified the source, (Staufer, p. 240) and he says steam struck the turbines a 'speed of two thousand miles per hour', perhaps the turbines didn't rotate at that speed; but then many marine turbines rotate at 6,000 r.p.m and the 6-8-6 turbines were an adaptation of marine power plants (Staufer, p. 241). Unsure if a loco's steam turbine rotating at 2,000 r.p.m. would deliver sufficient horsepower to drive a train at 100 m.p.h. Staufer has a pic of the 6-8-6 turbine at p. 241.

Unique?
[edit]The claim that the PRR S2 was the only 6-8-6 ever built was added by an IP in 2005, with no substantiation: Special:Diff/14994984. I don't especially doubt that this is true, but I can't find any source other than Wikipedia which makes this claim. It's not in Staufer's Pennsy Power, nor in Hagley's PRR Chronology, nor Don Ball's history of the Pennsylvania Railroad. Mackensen (talk) 16:45, 26 July 2015 (UTC)
- It's hard to find a source that says "there are no other 6-8-6s", but then there are no sources to even suggest there are any others, nor any credible likelihood of such. Andy Dingley (talk) 17:56, 26 July 2015 (UTC)
- Your point is well-taken. I've reworded. Mackensen (talk) 19:17, 26 July 2015 (UTC)
