<p>[quote user="MidlandMike"]</p> <p>As has been noted, the mechanics of a passenger train are such that they can operate in the push mode, whereas freights are expected to push slowly. However, with distributed power, I have noted engines at the rear moving at track speed. If the rear engine was not totally pushing the last cars, then why would it be there. How is that mechanically different than a back-up move?</p> <div style="clear:both;"></div> <p>[/quote]</p> <p>I think the key is that with Distributed Power, only the rear half* of the train is being shoved, and the rest is being pulled by the head end. That's still a considerable number of cars with today's trains, but it's not an entire train.</p> <p>*there was an article in Trains Magazine on this a while ago, and I seem to recall the cars in the center were being both pulled and pushed equally, reducing the number of cars being only pushed. Can anybody clarify this, or am I imagining things?</p>
