Things will get a little Harry Pottery in Comet county tomorrow morning when a classic steam train powers through.

Ferroequinologists – that’s steam train buffs to you and me – will be tickled pink when The Cathedrals Express makes a stop en route to York at Stevenage and Hitchin.

The Tornado locomotive, the first steam-powered train to built in 50 years in the UK will pick up passengers from Stevenage at 9.01am and Hitchin five minutes later.

Late sleepers can see the mighty engine on its way back to London at Hitchin at 8.12pm and Stevenage shortly after.
