Collection and Transportation of
The collection and transportation
of ballasts can be done by either of the following methods.
the ballast at ballast depots and transporting it to the site in ballast
l Collecting the ballast along the cess and putting the same on the track directly. The mode of collection is decided taking into account the proximity of the quarry, availability of good stone ballast, serving roads along side the railway line for the carriage of ballast, availability of ballast trains, turnround of ballast trains, and availability of traffic blocks for unloading.
1 Collection at Ballast Depots
The following procedure is
adopted when ballasts are being collected at ballast depots.
(a) The space
along side the railway line meant for stacking is divided into a convenient
number of zones and demarcated.
(b) For each
depot, a diagram indicating the site details of all the measured stacks is
stack in each zone is serially numbered.
of collecting and training out materials should not be carried out at the same
time in any zone.
ground on which the stacks are made should be selected and levelled.
should be taken for complete stacks. The measured stack should be identified
suitably by lime sprinkling or any other method.
(g) As soon
as a stack is lifted, it should be recorded on the depot diagram, which should
always be kept up-to-date. Challans should be prepared after loading the
ballast into wagons.
2.Collection of Ballast
Along the Cess
In case the ballast is collected along the side of the cess,
the inspector in charge should maintain a separate register showing the
measurement of stacks as well as its disposition (from km to km). The stacks
should be serially numbered between successive posts. Entries should be made in
a register whenever stacks are removed and ballast is put onto the track. The
record should state the place where the removed ballast has been used as well
as the date of removal of the stack. Materials passing through a 6-mm square
mesh are classified as 'dust' (limited to 1%).
