Re: DTC versus Track Warrants

You ask what railroads use NORAC rules.
As indicated in my prior posting, NS, CSXT and Amtrak operate under NORAC rules in the Northeast, along with commuter railroads like NJT, SEPTA, Metro North and MARC. Regionals/shortlines using NORAC rules include D&H, NYS&W, P&W, RBN&N, Conrail (Shared Assets) NEC, VTR, WNYP, FGLK, D-L, BPRR/R&S/G&W, M&E and Bay Colony.
Dispatchers issue Form D's to restrict or authorize any train movement over track described in Operating Timetables as "DCS Territory". DCS stands for - "Form D Control System." "DCS Territory" equates to "TWC Territory" on the railroads that operate under the General Code of Operating Rules.
