Yes, it would be better to meet on that side of the station - much nicer waiting down there rather than up on the A642.
Decrepitude might actually cause problems for
@Littgull and me after arrival at the station...
There is no easy exit from the York-bound platform - it is steps up to the A642, or over a footbridge to the other side. If my back is ok by then I will take our bikes over the footbridge and Brian can carefully walk over. If my back is still playing up then we might need healthy volunteers to do the bike transfers for us. I'll see how the back is nearer the time. If it is still iffy then details of the care package will have to be negotiated!
(Going home will not be a problem because access is good to the Leeds-bound platform.)
