    ... baseline system for the Midwest Regional Rail System, which is indeed for mixing higher speed passenger trains of the 110mph top speed type with slower freight, but particularly on more lightly used freight lines.

    When you have built a system so that it is compatible with a high volume of heavy 60mph freight and rapid 90mph freight mixing, mixing in 110mph passenger trains is mostly a matter of scheduling the slots. Since freight trains only have to stop to add more cars or change crews, 90mph freight trains and 110mph passenger trains are very close to the same effective transit speed.

    Mind, these corridors would be selected to move long haul freight, but if they happen to be useful for all or some of a passenger train route, that passenger train would run far more effectively on a Steel Interstate corridor than they do on the slow heavy freight corridors of today.

    •  Mixed passenger & freight trains? (0+ / 0-)

      Any reason not to put freight cars & passenger cars in the same trains? I assume they'd need different railyards at the origin & destination city, but surely that could be managed?

        ... to have them separate, though package express on Intercity Express Trains make make some sense. That would track what we used to do, since the post office typically carried mail on faster intercity passenger trains rather than on freight trains (that was mostly before the Great Slow Down, when the FTA tried to get freight railroads to adopt PTC and instead the freight railroads mostly just set their speed limit at 1mph below the speed where PTC was required).

        But given that even the rapid freight would have a lower speed limit than the 110mph passenger trains, and the passenger trains have more stops and starts than make sense for freight, combining the two makes for a single train that goes slower than either separately. When running separately, the higher top speed of the passenger train offsets the larger number of stops and starts.

        Combining general freight and general passenger traffic is more a thing for lower frequency and smaller volume routes, and under current conditions those would still be served by cars, buses and trucks. Though, if we bite the bullet on transport fully powered by sustainable, renewable energy, it could well come into the transport mix.
