Train Wash Machine Europe Makine systems

Metro train wash systems sized on cycle time per set

Europe Makine specifies a metro train wash on two numbers from your operation: the cycle time available per set and the length of depot road the wash can occupy.

How a metro wash is sized

Capacity on a metro plant is stated as cycle time per set. It follows from how often each set must be washed, how many sets the depot holds and the turnaround window between runs. Those three figures, with the set length, decide what the plant has to do in each cycle.

The second constraint is the road. The wash occupies a length of depot track, and that length is part of the specification. Modular construction lets the stages be arranged along the length of road the depot can give.

A full set on a single pass

Metro sets bring cab ends, roof-mounted equipment, door recesses and gaps between cars. Europe Makine draws the brush and nozzle layout to the vehicle profile so that all of these are treated as the set moves through once.

The layout is also drawn to the running line already in the depot: its track geometry, its structure gauge, its clearances and its electrification. The plant is built to fit what is there.

From depot drawing to quotation

  1. Share the depot drawing

    Show the road the wash will occupy, with its length, clearances and electrification.

  2. Share the set profile

    Give the rolling stock type, the set length and the number of sets in the fleet.

  3. Describe the operating pattern

    State the wash frequency, the turnaround window and whether the plant will be attended or unattended.

  4. Set out the water position

    Include the water supply, the site discharge consent and any recycling requirement.

  5. Receive the quotation

    Europe Makine returns a plant specified to your depot and your sets.

Water reclaim loop Used wash water drains from the bay floor into a collection pit, passes through settling tanks where solids drop out, then through filtration into a reclaim storage tank. A pump returns reclaimed water to the wash stages. Fresh water tops up the storage tank, and settled sludge is removed from the settling tanks.

Questions and answers

How long does a metro train wash take per set?
Cycle time per set is specified per project. Europe Makine sets it from your wash frequency and turnaround window and states it in the quotation.
Will the plant fit our existing track?
The plant is drawn to the existing running line, including track geometry, structure gauge, clearances and electrification.
Are roof equipment and inter-car gaps washed?
Yes. Cab ends, roof equipment, door recesses and inter-car gaps are treated on the same pass, with the brushes and nozzles laid out to the vehicle profile.
Can staff take over from the automatic program?
Every plant has a manual override alongside its automatic programs.
Which details set the cycle time per set?
The set length, the number of sets, how often each set is washed and the turnaround window at the depot.
