The Driver cab is a key area that needs ergonomic design because the driver needs to operate equipment, coordinate with platform staff, and see the track at high speed.
For example, when the driver is sitting, he should be able to see far enough of the track through the windscreen. Also, there is a side window provided so that on the platform, when the train is halted, the driver can see the station staff and the signals at the end of the platform.
The other key challenge for driver cab design is that the layout can differ from one cab to another to cater for differing equipment. Some of these requirements also come from the end customer.
The standard of ergonomics dictate that all the equipment and buttons should be reachable, and the windscreen should be clear enough to see the tracks in both sitting and standing position. Space for the drivers need not feel claustrophobic as they spend a considerable amount of time in the cab.
Safety, accessibility, ergonomics and legal requirements all contribute to the cab’s final design.
Apart from the ergonomic study, we support projects from design to completion. This includes concept design, detail design and release of design, as well as supplier coordination and build support.
Using an onsite and offshore development model to take into account the best cost option, we own the build end-to-end with our onshore people overseeing quality at all times. They will connect with the structural team, talk to the procurement team and help in identifying the supplier, and also talk to the supplier for manufacturability reviews. Once there is an agreement with the supplier, then we get the approval from the client. There is minimal customer drag in the process which is the key differentiator for Quest Global.
We not only look into the complete design of the driver cab, but we also ensure that it integrates well into the entire ecosystem, by providing the right support for electrical and electro-mechanical work.
The standards which we adhere to are the GMRT for the structural requirement of the cab and EN15227 for the structural stability of the cab.
