Q.What do you mean by Slip Siding?
If the Station yard is in a gradient steeper than 1 in 260 or there is a continuous falling gradient away from the station there is a possibility of vehicles standing in the yard entering or escaping into the block section and cause accidents to prevent such escaping of vehicles into the block section slip siding are provided.
At a station where there is a gradient 1 in 100 falling away from the station within 45 meters beyond the outer most points at either end a slip siding should be provided.
As per the schedule of dimensions no station yard should be constructed nor should any siding join a passenger line on a steeper grade than 1 in 260 except where it is unavoidable and then only with the previous sanction of the railway board obtained through the commissioner of Railway safety when a slip siding is made sufficient prevent accident.
