I've noticed a few oddities with the Frankfurt S-Bahn DB BR 143, nothing earth-shattering, but it would still be nice if it were different. -Why is the Frankfurt BR 143 listed as a separate Locomotive in the Locomotive selection and not connected to the Older Versions? - This DB BR 143 can only be used as a Substitute on certain Routes. I wanted to use it for a Service on Dresden-Riesa, but then realized that it can only be used on pre-TSW2 routes (Main Spessart Bahn, Rhein-Ruhr Osten and Ruhr Sieg Nord). Unfortunately, it is not available on either of the Dresden routes.
