<p>[quote user="carnej1"]</p><p>[quote user="Lars Loco"] </p><p>Right on Paul,</p> <p>but please consider, as you mentioned it, a steam-turbine-electric was never successful (water and electricity packed close together on a locomotive frame... ouch!). In addition, UPRR did some serious own research about designing good draft systems. In case of BB, the second run to Green River was easier and may have shown better boiler-performance. Instead of putting "fancy" gadgets on steamlocomotives, running lighter trains with them could habe been a better alternative.</p> <p>Cheers</p> <p>lars</p> <p>[/quote]</p> <p>While your statement holds true for the N&W and C&O coal fired steam turbines my understanding is that the GE and Westinghouse oil burning turbine electrics were technically successful. They were not however, economically competitive with their biggest oil burning competitor, the diesel electric locomotive..</p><p>[/quote] </p><p>From a theoretical standpoint, UPRR steam turbine 1+2 from 1939 were successful, too and could have been further improved, but they never made real money on the road (maybe some bucks for the GN, though)</p><p>Lars <br></p>
