Preparations are under way for Yorkshire Day, including a special Yorkshire-themed Pullman service, with Gill and husband Paul getting hands-on sorting out the event. There is also another big occasion on the horizon and Tim is organising the wedding of head boilersmith Mark and his equally steam-mad fiancée Emma. Their love blossomed because of mutual passion for steam, and in particular the B1, so they want the engine to pull them on their wedding train, but issues with the engine means it might miss the big day

The annual Gala Festival is staged, showcasing steam engines from up and down the country. As part of the events, the North York Moors Railway has agreed to swap its precious 100-year-old Q6 engine, the last example in the world, with an engine from the Severn Valley heritage railway. However, there is a problem as the Q6 is undergoing a two-year overhaul and is not ready. A crack has been found in the engine box, and there is no specialist steam copper welder available at short notice to fix it. If the Q6 cannot be sent to the Severn Valley, the entire festival may be ruined

Fiona Bruce and the team travel to Wightwick Manor near Wolverhampton, where more hopeful members of the public bring along their treasured antiques and collectibles to hear their stories and find out their worth. Items include a rare 18th-century lidded glass goblet and remnants of German parachute silk used in the Second World War for something other than its original purpose. There is also an appearance by former cricketer Ted Dexter, who brings in a special piece with a surprising family history

Fiona Bruce presents a look back at the most important and talked-about finds from the 35th series. Experts choose their favourites and there are updates on what has happened to the objects since they appeared - some have gone on to be sold, while others have been loaned to exhibitions. But it's not all about the antiques - the programme also provides a chance to catch up with some of the colourful characters, such as the 12-year-old collector of early lawnmowers
