From my experience being in “maintenance”, project managers make the same mistakes again and again, fail to clear snags (sometimes very major), think that temporary botches and work arounds can be accepted as the final product.
Blame maintenance when the new kit fails to work claiming what the were given at the beginning of the possession was faulty (it was not, voice tapes and data logs proved it at a meeting/post mortem)
Seemingly listen to the maintenance tech tell him that particular feeder is no good for where it is situated, tell him he’ll get it changed and then bullshit when it doesn’t and say its suitable for its current application.
Oh and the worst bit I’ve heard of was the level of pressure applied to maintenance managers to accept work into “maintenance” as finished when it clearly was not.
Sorry if this sounds a bit bitter but after nearly 20 years in the rail industry I’ve yet to see one project come in on time, on budget and actually work properly.
