Overview

The key challenges which OEMs face for building toilet facilities is interface control. This is because the toilet module comes from the supplier and needs to be assembled in the train. There is a space allocation given to the supplier to operate within, along with key requirements of whether it’s a universal access toilet or a space-saver toilet. 

 

The toilet is often a bought-out item, developed remotely by the supplier at their own pace. While designing the ceiling, the floor, sidewalls and the toilet interfaces, the question of how they come together is the main challenge. This can call for a lot of rework on the ceiling, floor and electrical wiring.

 

At Quest Global, we have the experience to support our clients’ needs. When we work on the ceiling or floor, we contact the supplier frequently to tell them what we are planning to do and get to know their plans. We also receive interim design models from the supplier and use the ongoing model as the baseline for our designs – which pay attention to aesthetics, usability, and accessibility for all. 

 

We act as an interface between the OEM and the toilet-provider, allowing information to flow both ways. This has helped by three things. Firstly, we provide them with the best practice an experience to help them deal with any potential issues from the outset. Secondly, we continuously monitor toilet designs and matching it with the designs for the rest of the train to cut down on rework. Finally, we increase level of project ownership by having mechanical, electrical and build support working together.

For eventful engineering careers redolent of memorable rail journeys, hop onboard.
