Hi again,   Is it possible two have two separate line speeds depending on the particular train ? Along the lies of " if train A is an express make it go at speed x through a station, for example. While, if train B is a goods make it go at a slower speed Y through the same station ?  I can't help thinking there is a simple solution but I just can't see it. As far as I can see all speed signs on the DLS are absolute (i.e. apply to all trains equally) and I've not seen any rules that can achieve this ? many thanks.
