same direction. If there are two trains moving in the same direction, the leading train must give up the track before the trailing train can obtain a track warrant for that territory. For example, if Train 56 has a track warrant to proceed in the northbound direction from MP (milepost) 14 to MP 77 and there is a train following, then Train 56 must give up a portion or all of its warrant before the following train can be issued the track that Train 56 has already cleared. Many times this is accomplished by the dispatcher asking the leading train for their milepost location and then issuing a warrant up to that point to the trailing train. Continuing the previous example, if Train 56 is clear of MP 50, the dispatcher can issue a warrant to the trailing train up to MP 50, but not beyond it. Once a train has received a new track warrant or has left track warrant territory they will release the entirety of their warrant back to the dispatcher.
317:. DTC was designed to facilitate the movement of trains using concepts of blocks and sidings previously used with train orders. DTC is only a mechanism to transfer movement authority and can work only within an arrangement of predefined blocks. Track warrant systems appropriate the remaining responsibility of train order systems to notify operating personnel of safety directives that include things like temporary speed restrictions, tracks out of service, etc. and combines them with the movement authority function of DTC. Furthermore, track warrants are not limited to fixed blocks and can be issued and released from almost any explicitly identified landmark along the rail line.

Track warrants usually allow a train to move in one direction only—a "proceed" instruction. Sometimes a train may also be given authorizing movements in either direction, called a "work between" instruction. However, only one train can have a section of track at one particular time if moving in the
