There has increasing emphasis on safety in Rail operations & increasing number of Rail dependent industries which call construction of large number of signaling installations. There are very few professional signaling companies who are competent to undertake construction of Railway signaling with stand alone technical capabilities.

It is in this scenario, Aster Private Limited ventured into the Railway Signaling arena in 2004 with its Railway Signaling Division, popularly known as RSD. Consequent up on de-merger the Railway signaling business was transferred to Aster Rail Private Limited.

Aster Rail comprises competent and dedicated Railway Signaling Technology team of 60, involving 22 signal Engineers, 34 Signal Technicians and other supporting staff. Aster Rail has a dedicated Maintenance team to mainly cater for the maintenance needs of the signaling systems of the private yards.
