Slowing trains down

[NW1776]

I know in the real world, the dispatcher and train crew can discuss if they need to slow down [or as they refer to it in my experiences "Drag your feet a bit"], is this a feature that can be implemented so that the train crew can slow up so they won't have to stop and go ahead and everything can move smoothly?

Yes, it can. There are other consideration for slower speeds (in TDP called something like "slow speed order") in development, e.g. in hazard areas, for instance high wind speed or flooding (very heavy rain). So sometime you may get a weather report/advisory for areas of your territory you have to act upon. We already have slow speed order due to track deterioration But all that is imposed due to external impact, not just to keep traffic smooth and save energy. We will consider that.

I was more referring to calling a train and telling them to slow down until they have a more favorable signal before continuing as to prevent having to start and stop at a signal.
