Diamond Seating Seating Overhaul and Refurbishment for the Railway Industry

Diamond Seating Limited (DSL) is a mass passenger seating overhaul and refurbishment company. Founded in 1976 DSL has grown to be one of the largest suppliers of overhauled public transport seating in the UK.

Seat refurbishment for the railway sector

DSL provides a range of services for the rail sector, including a full train refurbishment programme.

The comapny also offers seat stripping and maintenance including the removal of covers and / or foam from seats, and rebuilding seats with new foam, interliner and moquette cover.

Refurbishment of the driver and second man seats and of the drivers cab lining is also available. The seats can be fitted back into the train at the depot.

As well as seat replacement, Diamond Seating can also provide professional cleaning services, powder coating and glass-reinforced plastic (GRP) work, metal fabrication facilities and tables, seat shells and all ancillary items.

All operations conform to the current Railway Group Standard.

Corrosion and welding services

DSL is currently undergoing testing and approvals for a new modular seating design as part of its portfolio development.

This is a very different manufacturing process with infinite options to make the operator’s seat unique to them, while the core of the seat will be a standard design with off-the-shelf components.

To satisfy the demand of train owners and operators, DSL also offers corrosion and welding services. As the rail industry continues to grow, Diamond Seating will offer new solutions to public passenger services.

Certification and Compliance

With new regulations and materials being requested in the ever more complex interiors of trains, DSL have been proactive in hiring an experienced rolling stock compliance engineer.

In addition to working with Arriva Northern and helping them achieve a bench mark status for their fleets, DSL are working with a major leather supplier to produce a product that will achieve Cat1b fire certification, the timetable for this indicates a positive result by the end of 2016. This will be a first within the industry.
