I see the tour next Saturday has had its confirmed timings back with the return running around 90 minutes later than what was originally advertised.
Which for me is the final straw for booking on tours before the times get confirmed, especially as now it's a +14 into the last train to Walsall from Tame Bridge, and with railtour standard times that is too tight for comfort.
At least there seems to be at least one bus as a backup, although it will probably be just as quick to walk the ~ 3 miles. Changing at Crewe isn't much better, with the negative of putting me onto the vomit comet from New Street.
