    Wheel/rail contact patch is roughly the size of a dime for each wheel. The rolling contact is subject to fade out at faster speeds, hence the 30 MPH lite engine (on CSX anyway) speed. Not only can the signal circuits "lose" your movement, the crossing protection circuits can as well, causing the lights and/or gates to malfunction. "Back in the day", the same restriction also listed single RDCs. There was also usually a restriction not to stop with sand in the same rule or the next one to it.
