Question about US Diesel Locomotives

Phillip wrote to RTWP:
I had read somewhere that Alco roadswitchers could be shut down and started again like an automobile, but that early EMD units such as the GP7 had to be left idling when not in use.  Why is this, and how much fuel would have been wasted by this idling procedure?  What was the first EMD locomotive design to not have to be left idling during downtime?

  1. Thank you for your interesting question Phillip. As with many things in the railway business, there's not a simple answer but I've posted it in the blog on 29th July 2011
