How to work MFI, How to work UNIMAT ,Plasser India, Track machine,Indian Railway machine.

MFI is the tamping machine .It work on plain and point and crossing
UNIMAT Compact Split Head (MFI) (Plasser India).
Multi-Purpose Tamper (Plain and Points and Crossing Tamper) - This
machine is designed for spot attention on plain track as well as point
and crossing. These may have a flat platform at rear end with crane
facility for loading, unloading and transportation of P.way materials.
Various models of Multi-Purpose Tampers, presently in use on Indian
Railways are as given below-
(i) UNIMAT Compact (MPT) (Plasser India),
(ii) UNIMAT Compact Split Head (MFI) (Plasser India).

Tamping machine - Tamping machine measures the existing track parameters
and lifts it to enable correction of the cross level and alignment, to achieve target
or pre-determined parameter values, with an aim to improve the track geometry.
It simultaneously packs the ballast under sleeper(s), using tamping tools fitted on
tamping unit, to provide well compacted ballast bed.
(1) Functions - The main functions of tamping machines are-
(a) Correction of alignment,
(b) Correction of longitudinal and cross levels,
(c) Tamping of ballast under the sleepers.
Some of the tamping machines have additional fitments for track ballast
stabilization also.
