Nearlythree, bad news, my dad says Nigel Gresley isn't out until September as she needs some work doing to get ready for mainline running. In the meantime, he says all the little steam railways do Thomas days, co-ordinated around the country so everyone gets a go.
However, in September, NG is running from York to Bedford on September 15th, and then from Walsall to York the following weekend. And my dad will be driving! Apparently NG has a corridor tender, which means while you are travelling, you can walk along the train to the driver's cab if you ask very nicely.
He doesn't think Lady is based on any real engine, either, sorry, so you'll have to find a Thomas day out and hope they have something done up to look like Lady.
Btw, it's been lovely to 'talk' to your dd - so nice to find a girl who is into trains. Do you think she'd be interested to know my dad looked after all the steam engines for the Rocket 150 celebrations back in the 70s (150 years since Rocket won the Rainhill trials - kind of the launch of proper railways in this country)? We had a school trip to look at his engine shed which made me very proud.
Which part of the country are you in? Can find you a steam railway if you give me a clue!
Revd Awdry was lovely, btw, but sadly my father chucked out all his letters in a very misguided tidying up operation at some point.
