Hi All, I have been following threads for a while but this is my first time posting. I have been invited for my DMI on Friday at Orpington ( for Orpington ) it was a bit short notice and only have a week to prepare. I’m learning the TPWS worksheet and preparing answers based on the job description, company values etc
I’ve researched current projects, refurbished stations, volume of passengers transported, revenue generated and amount of staff employed but really struggling to find out information on the actual depot and I hate to say it but understanding the lines as I don’t really use the train
. Also when looking through the forum there is loads of example questions but I can’t get my head around all the abbreviations.
what is the definition of a metro line? What’s the deference between metro, mainline and high speed? TLK and GTR? What is a TOC? What is MTR?
what’s the difference between a managed and served station?
Any help would be much appreciated
