Very nice and remember these entering service on the Bed-Pan services. 👍 Seem to recall the bottom-hinged vents above the passenger sidelights on (some?) units being aluminim rather that glazed which always appeared to look strange. .
@@ewhurstgreen Hi, yes, I'd picked that up on some of the photos! Didn't really understand the reasoning, other than vandal damage or lack of spares! 🤷♂️
@@britanniapacificmodels7788 Never did look into the reasons why the original design used these, although I suspect it was down to a combination of siplicity and cost. Yet the earlier 313 units (and derivatives) had one-piece glass hoppers....
@ewhurstgreen the tiny quarter lights always seemed a bit of a faff and the glazing unit all seemed to be put into the full rectangular opening that the later units had. My guess is that it was thought that the larger hoppers would cause too many draughts!
@@britanniapacificmodels7788 Now you've mentioned draughts, I seem to recall the 313 units having problems with the hoppers being blown open when entering tunnels at speed..... Perhaps this may be why the first 48 units had metal vents? _(The second batch had glass hoppers)._
Another superb model of an EMU from Britannia, looking forward to my Class 310!
@DaventryParkway Thanks and I hope that you'll be happy!
