Railway Control System

Safe and Reliable Control Panel Manufacturing Solutions!



We are one of the best relay manufacturers in India, and we introduced metal to metal TM type signalling relays in 1987 for Indian Railways. With the technical collaboration with Integra Holding AG, Switzerland, we provide fail-safe solutions for the passage of trains through interlocking functions thereby replacing the old technology of mechanical lever frames.

We are an ISO 9001:2015 Certified company and an approved vendor for metal to metal TM type relays and Fuse Auto Changeover System as per IRS specifications of Research Design and Standards Organization (RDSO), Lucknow.

IEIL has executed important panel interlocking, route relay interlocking and Audio Frequency Track Circuit (AFTC) projects in the Indian Railways.

With the help of panel interlocking, medium-sized railway stations can prevent conflicting movements through an arrangement of tracks such as junctions or crossings. The panel interlocking from Integra Engineering, one of the best control panel manufacturers, is designed in such a way that it is impossible to display a proceed signal until the route that is going to be used is proven safe.

Route relay interlocking is a method of interlocking useful for large and busy stations. It can handle high volumes of train movements. Using route relay interlocking, an entire route through the station can be selected along with associated points and signals of the route. It can set all the process like receiving, holding, blocking, or dispatching trains at once with the help of a switch.

The audio frequency track circuit is a jointless track circuit which is specifically designed to meet the with the onerous immunity in AC and DC electrified areas. It also prevents the disturbance from a high level of interference present due to traction harmonics.

Also, Integra Engineering, one of the best relay manufacturers in India also supply various solutions like domino panels, AFTCs, individual and group relay directly to the controller of stores, Indian Railways and Konkan Railways. We have also executed export orders for our relays in the past.

We provide a fail-safe solution for the passage of trains through interlocking and group relay functions. Dustproof manufacturing facility and stringent quality checks provide superior quality relay products trusted and approved by RDSO and Indian Railways.
