Thes trains do not have 'grandfather rights' - so the H&S issues presumably
can be overcome if required - you can nearly always find an example of
something happening on the railway that they say 'isn't possible' somewhere
else...

The Whistling Fellsman tour - 13 Mk2's (plus a generator coach) - set
down at Denton last night with no problems.

But then there were plenty of stewards to make sure passengers were
moved forward to the first 3 coaches in order to alight safely.
