Carriage Washing Machines

A vehicle with a clean external appearance is pleasing to the eye and increases customer confidence that the train is well maintained. Environmental Scientifics Group has considerable knowledge and expertise in plant design and operation to ensure efficient and effective use of carriage washing machines.

ESG has developed a testing procedure which provides an objective assessment of the cleaning efficiency of the plant. This assessment is quantitative and allows plant operators to optimise the performance of the washing machines.

Infrastructure
ESG provides advice on new build installations and refurbishment of existing facilities. We provide advice on:

• Concrete apron design
• Corrosion protection
• Polymers, sealants and coatings
• Design of flails and brushes
• Choice of chemical cleaner types and setting ideal parameters for plant operation

Operability
ESG will audit plant to ensure compliance to recommended set-up criteria. We monitor:

• Cleaning performance
• Dimensional checks on flails and brushes
• Analysis of cleaning solutions
• Flow rate and pressure checks at washer jets
• Visual awareness of operations
• Calibration of chemical dosing pumps
• Water usage rates

Safety and the Environment
Handling and disposal of chemicals requires special training and routines. ESG provides advice on the following services:

• Compliance auditing of effluent discharges
• COSHH training in chemical handling
• Checking of water supplies for legionella bacteria
• Disposal of excess-to-requirement chemicals
• Advice on manual handling operations regulations

Performance Audits
ESG’s unique testing system provides a cleaning performance index of the carriage washing machine. Operators and train care managers can use this index in their cleaning specifications to ensure consistency of performance.
