I don't think there is a regular plan in place to turn the South Shore and Metra Electric trains ever. If so, how do the railroads avoid wheel wear? The South Shore especially is biased to right turns going inbound (timetable west starts out facing due east, turns south, west, then north to terminate in Chicago). Or is this not a big problem?

Believe the MED just grins and bears it, which would be why METX 1 has a permanently attached tomlinson coupler (instead of an adapter) for shuttling cars between the end of the BI branch to the wheel shop in the yard there. My guess is that the Electric cars are put in a constant rotation so they all hit the BI branch at some point and can be pulled out from under the wire to get the wheels worked on.

The South Shore has a similar machine at their shop, where you can turn the wheel right there while it's still on the truck: http://www.flickr.com/photos/davidfulla ... 3115710460.
