Rail Track Ballast is an essential part of any rail construction project. Rail Track Ballast is typically made from crushed granite which has been screened to remove undesirable fines thus creating a hard wearing, free draining and easily cleaned aggregate. Typically Rail Track Ballast is packed between, below, and around the sleepers by specialised equipment. It is used to facilitate drainage
· Good old Dartmoor granite from Meldon, or in the case of the SDJR line after about 1958 when the WR took over responsibility, it was the inferior stuff from the can get a good granite representative from most good model railway scenics outlets, such as Nick of Modellers Mate, packs come in 2Kg bags. Don''t use the bbq stuff, that''s better for ash pathways (cinderpath) or cess''s.
Ballast is the name for the ''stones'' beneath the track. This aggregate forms the trackbed and supports the track. It also helps with drainage, so rain water can drain away rather than pooling, and with preventing vegetation growth, which could destabilise the track and be a hazard for anyone working on the railway.
Types of Ballast The different types of ballast used on Indian Railways are described in the following Sand ballast Sand ballast is used primarily for cast iron CI pots It is also used with wooden and steel trough sleepers in areas where traffic density is very low .

Some light density railroad lines would appear jet black as nothing but burnt coal cinders were used to ballast the route. In any event, track ballast must regularly be cleaned or added as when dirt and grime builds up within the rock it reduces its ability to properly drain water. Ballast also acts as a support base for the railroad track structure giving it strength and rigidity but also
The stones that you are talking about are called as ballast in railway typical size of ballast varies between 65–20 mm with almost 98 % size greater than 40 mm. These ballast are laid under the sleepers (on which rails are laid),an
When cinders were available, they were used only on branch lines, sidings and in rail yards. Most main line trackage used gravel ballast instead of cinders because of durability. Cinders could quickly be ground into a fine powder by the movement of crossties as a train passed over them, and would then lose their drainage properties. Reply; wm3798.

The excessive use of railway lines for transportation poses a threat to the buildings in the areas near the tracks due to the immense vibrations the tracks experience when a high speed locomotive moves over them. Also, the loud noise that is produced when a train moves rapidly also the tracks is also a nuisance to the surrounding areas.
Large fleets of tampers and ballast regulators were introduced for maintenance and for renewals the new machinery consisted of ballast cleaners, rail cranes and tracklayers. In the 1980s new processes led to the introduction of stone blowers and dynamic track stabilisers. Following privatisation in 1995, we have seen major shifts in the use and type of track maintenance and renewal machinery
· Size of Ballast. The size of the ballast used in railway track varies from cm to cm. The stone of size larger than cm is not preferable due to poor interlocking property. The bestrecommended ballast is that which contains stones ranging in size from cm to cm.

Ballast is one of the main components in the railway transportation system, used to support the railway sleeper and rail track. Before laying tracks, a layer of ballast is needed to pave on the railway subgrade. The use of ballast is very available for water drainage and the track position adjustment.
Broken stone is a widely used ballast in railways. It is obtained by crushing hard stones like granite, hard trap, quartzite etc. In lieu of broken stones, limestone and sandstone can also be used. It is suitable for highspeed railway tracks.
freight line. Ballast is made up of stones of granite or a similar material and should be rough in shape to improve the locking of stones. In this way they will better resist movement. Ballast stones with smooth edges do not work so well. Ballast will be laid to a depth of 9 to 12 inches (up to 300 mm on a high speed track). Ballast weighs about 1,600 to 1,800 kg/cu/m.

The discrete element method (DEM) has been confirmed as an effective numerical method for modelling railway ballast, and successfully used to analyse a wide range of ballastrelated applications
Ballast – the stones beneath the track – is removed from the railway, from conventional work sites and by our High Output Ballast Cleaner Systems. These hightech machines travel along the railway at night removing dirty, worn ballast and replacing it with clean, more angular pieces. The dirty ballast is taken to a High Output Operations Base, and from here it is delivered to Whitemoor by
lines: spoil removal and ballast supply On singletrack railway lines, only the track under repair can be used to perform the ballast cleaning tasks. Thus, the removal of spoil from and the supply of new ballast to the worksite has to be performed both in front of and behind the ballast cleaning machine, respectively (see also Fig. 2). Spoil removal Material conveyor and hopper (MFS) units are
