But you're not doing that every hour, every day, 7 days a week. At the moment drivers change ends by walking through the train (185), with 68's that won't be possible (obviously). The risk involved in changing ends has therefore increased, and in this day and age you can't simply ignore that and hope all will be OK. TPE have to show that they have assessed the risk, and taken suitable steps to lower the risk as much as possible. Changing ends at Middlesbrough is not done in a lit siding, its done between Cargo Fleet level crossing and the first signal on the Nunthorpe branch. There is a walkway for going cab to cab between two units, but it isn't in the correct place for where the 68's would stop. Its not about drivers being "soft" or "awkward", its about the company understanding the risk and taking suitable action, covering backsides perhaps, but that's the modern world.
