North Central Railway Tender

a) Running track site:- Replacement of old sleepers and rails (CTR) by dismantling existing track of all types of sleepers by making 13m loose rail panel (or any suitable length panel) with existing sleepers & SH rail (for removing existing track) with wider base sleepers/revised wider base sleepers at density of 1660 sleepers per Km assembled with loose rail panel (or any suitable rail length panel of SH rail) in PQRS Depot and placing over ballast properly during traffic block after removing panels of old sleeper and SH rail of 13 m loose rail panel (or any suitable length panel) with the use of contractor's PQRS Machine by providing auxilary track with gauge of 3400mm (either with the use of existing rail from existing track or with new rail unloaded by contractor from EUR in block as instructed by SSE/P-way, (if required) over metal/ wooden sleepers, to be provided by Railway, 500 Nos./rail km on both rails at the interval of 2M) and providing fish plates for joining loose SH rail over wider base sleeper for continuity of track and maintaining track parameters as per Para 522 of IRPWM 2020 to keep the track fit for 30kmph. SH rail over new wider base sleepers/revised wider base sleepers to be replaced with new/earlier existing rail on running track (with replacement of rubber pad, liner & greased ERC and greasing of liner contract area. Grease to be used should be of 'o' graphite grease as per IS code 408). As soon as loose rail length of track reaches 500m/750m (as per decision of Railway site engineer i.e. SSE/JE/ P-Way), loading of track panel (SH rail over old normal sleeper and tied with ERC) of approximately 13 m length over Railway wagons and unloading of track panels of the length of 13 m (or any suitable length) and wider base sleepers/revised wider base sleepers will be done during traffic block. TRR with the rail of the length of 250 m to 500m (preferably 20rail panel) will have to be done as soon as track of loose rail exceeds 500m length. Further the contractor will follow instructions of SSE/P-way to relax speed of track upto maximum speed of section as per schedule laid down in IRPWM 2020 para 708 for Machine Tamping with all machine packing related works such as recoupment of crib ballast, shoulder ballast, boxing and dressing. The whole process will continue till completion of work. Auxilary Track (AT) will have to be removed with advancement of CTR work as per direction of Railway (SSE/JE/P-Way). b) PQRS Depot: - Track panel with SH rail of 13 m or any suitable length over wider base sleepers/revised wider base sleepers/revised wider base sleepers will be made with necessary fittings in PQRS Depot. Loading of these panels over Railway Wagons and unloading of released track panels (released from running track) consisting of all types of rails & sleepers from Railway wagon at PQRS depot using Contractor's own portal crane including dismantling and stacking each component of track properly at designated locations.
