For full details, see GE/RT8000 Rule Book module TW Mixing Classes of Dangerous Goods Some wagon and container loads of dangerous goods are prohibited from being on the same train as other dangerous goods. These prohibitions are shown in Appendix 2 of this manual. 1.5 Separation (a) Separation Distances - Requirement Wagons and containers carrying certain types of dangerous goods must be separated on the same train from other wagons and containers carrying certain other types of dangerous goods. These and any separation distances required at the front or rear of the train are shown in Appendix 2 of this manual. (b) Separation Wagons - Meaning In this Section, the term 'separation wagon(s)' or containers covers: - empty wagons or containers wagons or containers carrying certain non-dangerous goods Working Manual for Rail Staff Handling and Carriage of Dangerous Goods Page C2

(c) Separation Wagons - Requirements all separation wagons must weigh more than 8.15 tonnes a brakevan must not be counted or used as a separation wagon. (d) Separation Exemptions for Trip Working (Non-Explosives) Separation wagons are not required for trip working: - where the length of the journey does not exceed 5 miles, or where the length of the journey does exceed 5 miles and authority has been received from the Train Operating Company and the Infrastructure Controller(s) concerned. (e) Separation Exemptions for Trip Working (Explosives) Some separation wagons are not required for trip working. These are: - between the locomotive and the first loaded wagon between the last loaded wagon and the brakevan (if provided) behind the last loaded wagon (if there is no brakevan).
