Leftover work from #9712

Composition codes can affect the max speed of a train. For freight trains, here is the mapping :

Code	Max speed (km/h)
HLP	100
MA80	80
MA90	90
MA100	100
ME100	100
ME120	120
ME140	140
ME160	160
MVGV	200

AC

• The table above has been implemented and changing the composition code update the max speed if the chosen code is supposed to lower it. User's input are still not overwritten.

This is the mapping I observe on staging

Code	vMax	Diff ?
HLP	100	x
MA100	100
MA80	80
MA90	90
ME100	100
ME120	120
ME140	140
MV160	-	x
MVGV	200	x

Which is not exactly the one from the table. Did it change @axrolld @Wadjetz ??

The differences are :

• Value for HLP
• Value for MVGV
• For ME160 in the issue table, we have MV160 in the list in the app, and the value is None instead of 160

My bad i forgot to update the issue main body after this comment. I just did the fix. Good catch !

Now it's correct then :) And for the points 2 & 3 they seem corrected as well. I validate the ticket !
