  •  Re: Dedicated track (8+ / 0-)

    Our resident train expert BruceMcF occasionally points out that dual freight/passenger systems work out okay, even if running at significantly different speeds, as long as sufficient passing track is added.

    In one diary he mentioned a number of 10 miles of passing track per 50 of main track.

    That way, with modern switching and scheduling technology, the freight trains and passenger trains can be organized to bypass one another.

      ... though another part of the equation is how committed the host railroad is to keeping the train moving on time if it can. Unfortunately for the Starlate, it runs a long ways on Union Pacific track, and between the two main Western railroads, Union Pacific is much worse about allowing the Amtrak trains to run on time.

      In many cases, the 10miles in 50miles systems that is the baseline design for the proposed 110mph Midwest Regional Rail System run on lines that are secondary routes for the big railroads or the routes of short lines who will happily give the passenger trains priority in return for help with maintaining their track.
