(...) Yikes! Did you mean for your response to Jason's joke to sound so venomous? I didn't think the discussion was intended to upset. Also, for die-hard, steam fans, steam may have lost, but it's far from dead, and who knows, it seems it could (...) (23 years ago, 31-Oct-01, to lugnet.trains)

(...) I'd take serious challenge to that statement. The best steam only power plants are in the 45-47% range of effiency (input to output). Mind you, they DON"T MOVE!... When done correctly, steam has a cycle effiency of ~12% on the rails (I can get (...) (23 years ago, 1-Nov-01, to lugnet.trains)
