Lumding station yard re-modeled to increase speed from 15 KMPH to 50 KMPH

The entire Lumding Railway Station Yard was recently re-modelled by the Lumding Division of N.F.Railway in-tandem with the recently completed Gauge Conversion work of Lumding – Silchar section. The entire re-modelling work was completed smoothly within a record time without interfering with the running train traffic.

Prior to Gauge Conversion, Lumding Railway Yard had both BG and MG yard. MG yard had passenger as well as freight handling and transshipment facilities. MG passenger yard had o­ne island platform, o­ne end platform, o­ne stabling line and o­ne washing-cum-pit line along with Sick line complex. In the BG yard in the station, there were 3 platforms, o­ne freight through line and 2 spurs for Accident Relief Train and Accident Relief Medical Equipment van. Besides there was a BG Reception & Despatch Yard, o­ne IOC siding taking off from the main line and a Transshipment Yard. The yard was operated through o­ne Central RRI Cabin, o­ne South Cabin, o­ne B-Cabin and o­ne A-Cabin. Central RRI Cabin was manned by o­ne ASM and o­ne Porter in 8 hour shift. The other 3 cabins were manned by o­ne ASM and o­ne Pointsman each in 8 hours shift. Over and above, 3 ASMs were deputed o­n platforms duty in 8 hours shift supported by o­ne Porter. Lumding Yard was spread over 4.5 KM with multiple gradients of 1 in 150, 1 in 200 and 1 in 400.

                After completion of the remodeling work, there is a central Vishual Display Unit (VDU) with Electronic Interlocking (EI) with a spread of about 2.3 KM. All other cabins have been done away with. There are 10 lines in the BG Yard with provision of 5 platforms, 3 Reception & Despatch through lines and 2 dead ended Reception & Despatch lines (dead end towards Tinsukia). The yard has now been made more compact and regarded so as to ease the gradients in the yard with gradient not steeper than 1 in 400 (as stipulated by Railway Board for all stations).

The permanent speed restriction of 15 KMPH in the yard has been removed.

The entire yard is now laid with 60 Kg long welded rail as compared to short welded rail with Fish plated joints in the MG yard.

One Level crossing gate, ST-49 has been eliminated by construction of a Limited Height Subway (LHS) with Barrel length of 41 m, Carriage Way of 5.2 m and Height of 4.25 m.

The Vishual Display Unit (VDU) of Electronic Interlocking (EI) has been commissioned in a new building with separate Relay Room, Battery Room, Data Logger and IPS. There is a hot standby of the VDU in order to take care of any contingency.

Outmoded Route Relay Interlocking has been replaced with state of the art Electronic Interlocking (EI) having 190 routes, 38 Multiple Aspects Colour Light Signals, 34 Shunt Signals and 50 Point Machines. As a result signal failure at Lumding will decrease substantially resulting in improved punctuality and reliability.

The Standard of Interlocking has been upgraded from Standard – I to Standard – II@R, thereby facilitating increase in speed through the yard from 15 KMPH to 50 KMPH. It will also facilitate running of trains through the yard without stopping at a much higher speed.

As a result of this compaction posts of 10 ASMs, 10 pointsmen and 4 Gatemen will be saved resulting into saving of Rs. 88,92,72/- annually.

An area of about 30,000 square meters have been dressed up in the yard between the lines where it is proposed to develop a “Nursery” and thereby a green belt. This will beautify the yard and at the same time save the land from further encroachment.
