“Infrastructure upgradation on war footing is our top
priority”, says ShriVishweshChaube, GM Northern Railway.
Without disrupting running trains, Ten Bridges
were rehabilitated and repaired Following the
directives of ShriChaube by Moradabad Division
of Northern Railway within an extremely short
time period of 3 months that too without causing
any significant disturbance to movement of
Shri Chaube created a systematic plan to do such major rehabilitation work by forming a team of multidisciplinary officers captained by their respective heads of Department. By keeping a very close watch on the entire exercise so that the allocated “Mega Block” time is not exceeded under any circumstances, ShriChaube ensured that the planned maintenance works were completed right down to the tightening the last nut on the tack fishplates.
Some of the important repair works completed recently on Laksar-Dehradun, Raiwala-Rishikesh and Moradabad-Saharanpur Sections:
·Provision of centralized bearings on Bridge no 3 (8x18.30 m plate girder) on Rishikesh-Raiwala Section.
·Replacement of rail cluster has been done with RCC slabs at Bridge no 134 (1x1.52 Rail cluster) on Laksar-Dehradun Section.
·Replacement of rail cluster with RCC slabs has been done on Bridge no 136(2x 1.38 Rail cluster) on Laksar-Dehradun Section.
·Rebuilding of bridge with RCC box segments has been undertaken on Down line Bridge no. 1215 (2X3.05 m) RCC slab on Moradabad-Saharanpur Section.
·Rebuilding of bridge with RCC box segments at Bridge no 1218 DN
(2X3.03m RCC slab) executed on Moradabad-Saharanpur Section.
·Yet another major bridge work was executed at Dhanetaand work on replacement of steel girders by PSC Slab on Bridge No. 899 was also completed using 100 MT Road Crane in running water stream on Rosa-Lucknow section during December 2017.
·Apart from these bridge repair works, staff and officers of Moradabad
Division also worked tirelessly towards completing work of Foot Over Bridge at Moradabad railway station as part of the safety agenda during last quarter.
·The Re-building of Bridge no 1218 DN (2x3.05m) with pre-cast RCC box segments at KM 1482/18-20 between Bundki and Nagina stations on Moradabad-Saharanpur DN line has also been successfully completed within a record time.
“Well executed maintenance work can only be achieved by meticulous advance planning” said ShriChaube. During December 2017, ShriChaube guided officers of Moradabad division to undertake and complete the massive work of replacement of all four girders of a major bridge no. 1076 (4 x 12.2 m)in one go alongwith replacement of bed blocks and centralized bearing– a feat that has not been seen in the recent past. This bridge, located at Dhaneta Railway Yard on the Moradabad-Lucknow section, carries all mainline mail express passenger and goods traffic. What is commendable is that the mammoth task of replacing the girders of this bridge was carried out in one shot by deploying two high-capacitycranes and hundreds of skilled and semiskilled staff in strategically plannedsequence without exceeding the allocated time for “traffic Block” by even a minute.
In the recent maintenance works of these ten bridges, activities involving
dismantling of existing track, dismantling of abutments and central pier, removal of debris, laying of sand layer as levelling course, placement of pre-cast RCC slabs and box segments, Backfilling along with associated works namely backfilling cess repairs and then finally re-linking of re-laid tracks were done by gangs of workmen working with clockwork precision.
Especially remarkable is the fact that while the work of bridge repairs was being done, all the other track assets, signals and OHE structures on these affected lines were also concurrently repaired in what is known as “Shadow block”. Teams deployed in tandem for doing work in such a shadow block did complete track renewal of Point no-60/B in Nazibabad Yard, replaced a fractured rail at km 1509/6- 8 by welding it in-situ. These repairs alone removed a long-standing speed restriction on running of trains that had to be imposed due to degraded track. As a result, trains are now running on this section at faster speed.
Besides these, extensive repairs were done at MuzzampurNarain Yard by using heavy machinery and two rails were replaced on Bundki - Nagina block section using the opportunity of shadow blocks.
