I've noticed that the NJT Multilevel Cab car will not apply traction until the brakes are in release, and with a considerable delay, leading to an inevitable rollback. This makes it difficult start even a small upward grade, and impossible if you are stopped in the uphill approach to NY Penn. I feel like the cab car will let the traction load up when in EP-hold to prevent roll back, similar to how you would start uphill from the locomotive. Am I missing something?
