The problems began with the live cable, which was clipped by a 28-ton tamping machine.

They had previously owned six other tamping machines, which were acquired between 1959 and 1975.

This is, in the mechanized age, usually done by a ballast tamping machine.

After that has been done, he said, a new top layer of hot asphalt can be applied and then compacted with a commercial tamping machine.

Retains correct track geometry for a longer period than was achievable using tamping machines alone.

This type of straight-track tamping machine is the oldest of the varieties.

Before tamping machines were made, tamping was done by lots of people with shovels.

They are also used for transporting diesel powered equipment such as track tamping machines through tunnel sections.

Straight track tamping machines:

The first Tie Tamping Machine in South Central Railway was introduced on January, 1981.

Universal tamping machines (U.T.)

Continuous action tamping machines (C.S.M.)

Points and crossing tamping machines (UNIMAT )

Multi-purpose tamping machines (M.P.T.)

A ballast tamper or tamping machine is a machine used to pack (or tamp) the track ballast under railway tracks to make the tracks more durable.

These tramways are quite advanced technically, with hand-me-down rails cascaded from the normal rails, remote-controlled brake vans, concrete sleepers in places, and tamping machines in miniature.

A Continuous Tamping Machine (CSM) can pack two sleepers at a time in a continuous mode and can pack (tamp) about 1.2 km of track per hour.

Maintenance of track including ballast cleaning and tamping, rail inspection, welding, grinding and milling, and operates and leases a variety of machinery such as tamping machines, cranes, grinding trains and ballast cleaning machines.
