But the article suggested otherwise. On the prewar equipment, you could use "electric hold" which would vent the system (and allow you to charge back up) and it would only hold your ten pounds in the cylinders while the pipes themselves were in full release.I think whoever wrote the article wasn't really paying much attention and didn't understand what was being explained, but for the matter of the article, it really didn't matter much. The old journal bearing equipment would allow you to actually fully release at a stop and the journal bearings had so much internal friction that you wouldn't roll anyway unless you were on a 2% or higher grade. But if you didn't service quickly if you DID roll, your train would dump as a lesson not to do that the next time you stopped there. :) |
