Level Crossings JE W – Induction – Ph – II 1. 0
Level Crossings • Level Crossings are one of the bottlenecks in Rly system but very critical asset for Engineering Department. • Separate chapter (no. 9) in IRPWM on Level Crossing
Importance of LC for Engineers • Majority of the LC’s are manned by Engineering deptt. • Even on Operating LC Gates, most of the issues pertain to Engg deptt. • These LC’s are the most inspected asset of Railway by various department. • Engg deptt are most vulnerable on this aspect- has to defend for the complaints by driver/station master, officers of other department for inattentive GK’s.
Important Aspects of LC • Classification of LC • Census of LC • Track Structure • Civil Infrastructure at LC • Gate keepers • Inspection of LC at stipulated frequency • Periodic Overhauling of LC
Classification of roads (Para-903) • Class I --- National Highways, State High ways, Important roads within municipal towns , roads in around towns where road & rail traffic is heavy. • Class II --- Major & Other district roads, Unimportant roads within municipal towns, roads within nonmunicipal towns including those within shunting limits, other surfaced roads. • Class III --- Earth roads & cart tracks. • Class IV --- Cattle crossings & footpaths.
Classification of LC Class Criteria Min No of GK Special Class TVU > 50, 000. 3 ‘A’ Class TVU 50, 000 - 30, 000 Or Line Capacity utilization 80 percent (On single line) and Number of Road Vehicles greater than 1000. 2 ‘B’ Class TVU 30, 000 -20, 000 and No. of Road Vehicles >750. ‘B 1’ Class TVU 30, 000 -25, 000. ‘B 2’ Class TVU between 25, 000 - 20, 000. ‘C’ Class All other Level Crossings for Roads not covered in above classes. ‘D’ Class - Cattle Crossings 2 2 (1 if closed at night)
Line Capacity of a Section Line capacity : Number of Trains that can be run on the section in 24 hrs. = 24 x 60 x 85 L + 5 100 Ø Where L = Maximum time taken in minutes by longest goods train to clear longest block section. Ø 5 minutes added for block instrument, which will not be added in case of automatic block section.
Traffic Census of LC • As per correction slip no. 100 of IRPWM, • Periodical census of all LC`s (Manned/Unmanned) Once in 3 years • LC`s Census taken for One week. • Census is taken for TVU (train Vehicle Units) per day
Calculation of Census of LC • Total no. of train units in 7 days (T) where Each Train is taken as 1 Unit. • Total no. of Road vehicle units in 7 days (R) • Each Four wheeled Motor vehicles, Bullock Carts & Tongas considered as 1 Unit. , Each Cycle Rickshaw/Auto Rickshaws considered as 1/2 Unit. • Motorized two wheelers are considered as 1/4 Unit. (Correction slip no. 144 of IRPWM) • Thus, Census of LC in TVU per day = (T x R)/7 • Census to be carried out by Multi-disciplinary team consisting of representative of CE, S&T and Traffic. • Mechanism shall be set up by DRM to ensure that the representatives are present for the census. • TVU census may also be planned using CCTV camera by outsourcing this activity.
Traffic LC Gates • Manning and operation of LC gates between the outermost stop signal shall be under the control of Operating Department. • Civil Infrastructure (Road, Gate Lodge, water, toilet & drinking water facility etc) pertaining to these LC gates shall be maintained by the Engineering Department. • Competency certificate to GK will be issued by TI & SSE/Sig (for interlocked gate) and countersigned by AOM. • Validity of comp certificate-3 years • Medical category of GK- A 2 (used interchangeably as Pointsman)
Engineering LC Gates • Operation and maintenance of LC’s beyond the outermost signals shall be under the control of Engg Deptt • Competency certificate to GK will be issued by SSE/P. Way & SSE/Sig(for interlocked gate) and countersigned by ADEN. • Validity of comp certificate – 3 years • Medical category of GK- A 3

(2 Nos. per day as against One per day during same period last year). This shall enhance safety and improve mobility of train operations. Rajdhani route to be upgraded to semi-High speed route – 160 KMPH The road surface on LC shall commence use of Rubberized materials at par with global standards which allow smooth passage of Road traffic at busy LCs hence improving mobility.
