  "text": "The railway undertaking must define the rules and procedures to be followed by his staff so as to ensure that the train is in compliance with the allocated path.\nTrain composition requirements must take into account the following elements:\n(a) the vehicles\nall vehicles in the train must be in compliance with all the requirements applicable on the routes over which the train will run,\nall vehicles on the train must be fit to run at the maximum speed at which the train is scheduled to run;\n(b) all vehicles on the train must be currently within their specified maintenance interval and will remain so for the duration (in terms of both time and distance) of the journey being undertaken;\n(c) the train\nthe combination of vehicles forming a train must comply with the technical constraints of the route concerned and be within the maximum length permissible for forwarding and receiving terminals;\n(d) the railway undertaking is responsible for ensuring that the train is technically fit for the journey to be undertaken and remains so throughout the journey;\n(e) the weight and axle load;\n(f) the weight of the train must be within the maximum permissible for the section of route, the strength of the couplings, the traction power and other relevant characteristics of the train. Axle load limitations must be respected;\n(g) the maximum speed of the train\nthe maximum speed at which the train can run must take into account any restrictions on the route(s) concerned, braking performance, axle load and vehicle type;\n(h) the kinematic envelope;\n(i) the kinematic gauge of each vehicle (inclusive of any load) in the train must be within the maximum permissible for the section of route.\nAdditional constraints may be required or imposed due to the type of braking regime or traction type on a particular train.\nThe infrastructure manager must inform the railway undertaking of the changes on characteristics of the allocated path change, as soon as these changes occur. The elements that must be checked in order to ensure the train’s compliance with the allocated path are set out in Appendix D.",
