Hello, everyone. I'm interested in how can I become a customer service assistant, whether rail / underground. What are the neccessary documents and training courses, which i need and all further infortmation will be very useful for me. In official sites usually will not positions, but I see new station employees everywhere and I am sure that, as in other serctors is applied and starts in agencies. Can a little more information than familiar, please? By Night Tube and Crossrail, I'm sure will be looking for people. Thank you in advance and lovely Sunday.
