WORKSHOPS, DEPOTS AND MANUFACTURING
View inside the depot showing the fuel modules, CET modules and oil and coolant dispensing points
effi cient when compared to a number of currently installed train washes and in certain circumstances can prove cheaper to run without a recycling system.
Oil & coolant systems
The in-shed servicing activities include the top-up and replacement of both oil and coolant. The dispensing systems are fed from centralised duty/standby pump sets, mounted within the plant room, which are fed from local storage tanks. The 25,000 litre capacity self-bunded oil tank is fi tted with a heater to ensure the oil temperature remains above 10C,
so pumping performance is not
compromised. At each dispensing point is a hose reel with trigger nozzle, complete with control to start and stop the pumps as required; also provided is local tank level indication. Oil and coolant draining is carried out in roads 3 and 4, with each system utilising an
air operated pump
CET pumps with macerators serving three roads
system to convey the waste product back to the storage tanks. If the tanks are full the system automatically shuts down and provides a warning to the operator.
Coolant mixing plant
As part of the package, the depot elected to have the glycol delivered neat in 1,000 litre IBCs. This necessitated a coolant mixing plant to provide coolant at a 33% mixed ratio. The mixing plant is situated in the plant room and produces mixed batches in 1,000 litre quantities, which it automatically pumps to the storage tank outside. Other than changing the neat glycol IBC when it is empty, the whole of the operation is automatic.
Compressed air
Airquick started in business in 1974 with a distributorship for Atlas Copco compressed air products, and has installed hundreds of
Fuel tank farm (three 115,000 litre tanks)
compressed air systems over the years.
Reading depot required compressed air points in the pit roads for servicing the train brake systems, air bag systems and light air tool use. At the heart of the system are 2 Atlas Copco GA 30-13 Work Station compressors with Elekronikon II controllers and CD desiccant air dryers, which incorporate the very latest in energy saving technology. The systems are linked into the BMS and will automatically shut off and vent the air down in the event of a fi re alarm activation. Delivering the project on time was a major priority and was achieved by a combination of a very successful working relationship with both Volker Fitzpatrick Ltd and Network Rail, allied to effi ciency of the design and the expertise of the installation team.
