RAILWAY INDUSTRY TRAIN PLANNING LEVEL 2 TRAINING Module 4 - Train Planning (Core Skills)
Train Planning Elements ROTR ROTP Point to Point timings (SRTs) Headways & Margins Graphs and Timetables
More on this Tomorrow Rules of the Route Contains Location, number, times and duration of major engineering work planned on the track for the timetable in question Any pre-planned temporary speed and/or other restrictions on the trains Any alternative routes or stopping patterns which will be necessary More on this Tomorrow
Rules of the Plan Comprise matters necessary for trains to be planned and scheduled Timing margins, junction allowances Timing points – mandatory/conditional Headways Station dwell times (min and/or max) Vehicle restrictions e.g. speed, routing, weight, length Advice on obtaining freight train loads and lengths Route opening hours Does not contain SRTs
Point to Point Timings (Timing Load) Basis of Calculation Distance between timing points Speed Gradients and other geography Power of train, locomotive, unit Load of train Train classification Additional time for permanent speed restrictions

Headways & Margins Headway - the minimum time between successive trains travelling “on green signals” on the same line. Determined by the time taken to travel between two signals (or signal boxes). Margin - the minimum time between trains at a location where the routing of one train takes it across the path of another.
Confliction Is a situation in which the path of one train runs through the path of another train travelling in the same direction, opposite direction (e.g. single line) and/or at a crossover/junction
