When a signal has a speed attached, the following applies:
SLOW - 15 Mph
MEDIUM - 30 Mph
LIMITED - 45 Mph
CLEAR - Track Speed
APPROACH - Trains exceeding medium speed must immediately reduce speed to 30 Mph as soon as signal is visible. Prepare to stop at next signal.
STOP - 0
RESTRICTED PROCEED - RESTRICTING - 15 Mph looking out for obstructions, 20 if not on a turnout.
Intermodal Trains - 60 Mph
Welded Rail trains (loaded) 40 Mph, 10 Mph through truss bridges, over turnouts.
Empty Non Intermodal Trains - 50 Mph
Unit Trains of coal, coke, iron ore - 50 Mph
Single Engine and no cars - 30 Mph
Side Dump cars (generally) 30 Mph
All tracks other than main tracks on CSX are 10 Mph, unless otherwise noted in special instructions.
Engine Tracks & Servicing Tracks - 5 Mph
Other Railroads or other locations on CSX may have slightly different restrictions than those here.
At specific points (found in our timetable), there are measured mile markers along the right of way, that we use a stop watch to check our speed. Most of the time our speedometer is accurate, but we still check their accuracy on every trip.
