I thought rail profiling was supposed to alleviate a lot of this as the train's wheels would sit in the rail profile better vs. a unprofiled rail (i.e.: a rail that was recently replaced and not grinded)In a perfect world yes, however we do not live in a perfect world. Wheel and rail profile is not the only issue that need to be taken into consideration, center of gravity is also a significant part of the equation. The high center of gravity the GG1 had was one of the reasons why it was so successful. John in the sand box of Maryland's eastern shore. |
