Add A Follow Shape/Track Gizmo

People Quite Like Railway Based Games So You Should Add A Follow Mechanism So You Lay Out A Track When Editing The Circuit And You Should Be Able To Add Signals Or Switches Or Incline/Declines In The Track And Add An Option For Stations. There Should Also Be Float Outputs Telling You How Far Away You Are From A Station In Either Miles Meters Or Kilometers And A Float Ouput Telling You What Speed Limit You Should Be Going, How Far Away The Next Signal Is And A Float Telling You How Steep The Incline/Decline Is In Either Ratio Or Percentage. If This Evtually Ends Up Getting Added Can You Add An Option For What Kind Of Train Like Electric/Desiel/Steam And If Its Steam Have An Option Were You Have To Keep The Pressure Up With Coal And Water.
