If this is right, I genuinely don’t understand it. In my job I get lots of instructions from my managers and I carry them out. In this case are the instructions not given?
We are taught how to check if the Aircon is working, how to set it to high cooling and what to do in order to help manage the train environment.
The train environment is rather dynamic so a one size fits all instruction won’t work.
The aircon could be working but if it’s really hot and you’re working a service that you know will become full and standing (and therefore very stuffy) then guards will often do a walk through to isolate the vestibule doors and open the windows.
That guard then hands over to another before the overcrowding ends and the new guard will likely assume that the windows have been opened because the temperature inside was too hot.
We’re also issued warm weather guidance.
In warm weather I always used to do an aircon check in each coach to see if I could do anything.
Obviously, some guards won’t do this.
Other times there’s no time to piss around with the aircon as there’s quite a number of priorities that come above this.
