Railway air conditioning service and maintenance

Keeping cooling on track for passengers

Our railway air conditioning servicing and refurbishment centre at Wimbledon is equipped with state-of-the-art facilities.

With 30 years experience in this specialist sector, we have developed extensive knowledge and unique engineering skills on the requirements of railway air conditioning systems.

Cooling London’s Underground

As a result, we carry out work on behalf of many of the major UK rail carriers as well as the London Tube operators.

Regular servicing and maintenance is essential to ensure railway air conditioning systems continue to perform well, and deliver comfortable conditions for passengers.


Our long experience, coupled with excellent engineering and testing facilities, ensures that railway air conditioning systems sent to us for refurbishment are processed and returned to service in tip-top working condition.

Once systems have been serviced or refurbished, we carry out a monitored full load test, to ensure the unit performs to specification.

Specialist remanufactured compressors for transport

We supply fully remanufactured compressors with special oils and paint colourings to meet the stringent approval processes necessary in this safety-conscious industry.

Higher standards of performance

The investment and risks involved in transport infrastructure procurement have driven the industry as a whole to demand higher standards of performance. LH-plc is registered and accredited by Link-up, the largest supplier registration and qualification scheme within the UK rail industry.

The principles behind the Turbocor compressor are completely different to conventional compressor systems. The high performance technology has proved to be exceptionally reliable, but when it needs servicing it is vital to use trained specialists or it can result in very serious problems.
