[quote user="edblysard"] Paul and Bucyrus... Was on a SD70M today, decided to nose around the nose if you will, and discovered a rather welcome thing. The collision post on these guys are huge....located in the same place as on the GE, they are incorporated into the structure of the nose...from inside the nose door they appear to be the sides of the compartment itself, about 3 feet deep at the base. Once you do a little looking, you realize the "walls" of the hall in the nose are solid steel, about 2 to 3 inches thick, as I said, about 3 feet deep and 6 feet tall. The sides of the nose cone and the front of the nose are welded to the post, although slabs would be a better description. The entire structure, slabs included is welded to the locomotive bed, and the post or slabs continue down and are welded to the frame. To give a comparative example, you could cut 3 or 4 sets of the GE post out of one side of the posts in the EMD. As the photo posted earlier in the thread of the UP locomotive involved in the Metro Link wreck shows, they can take a huge impact. Didn't have my camera with me at the time or I would have got a few photos.  will try to get some later. <div style="clear:both;"></div> [/quote] Ed, It sounds like there is a minimum required collsion post system specified by regulating agencies, but the locomotive builders are free to exceed the minimum.  From your information, it sounds like EMD has exceeded the minimum further than GE.
