Flying Scotsman is back in Oxfordshire this weekend

The locomotive, which spent much of the last few years undergoing repairs, will be passing through Didcot twice on Saturday due to a change in its route.

Originally set to join the Cotswold Line after leaving Reading, it will now travel along the former Great Western Railway main route instead, stopping at Reading and Didcot to pick up passengers before carrying on to Swindon.

It will then take the line to Kemble and into Gloucestershire.

The Flying Scotsman is due to leave Paddington at 7.40am and reach Didcot at 9.08am before arriving at Worcester at 11.50am.

On the way back, it leaves Worcester at 4.13pm, reaches Didcot at 6.36pm and arrives at Paddington at 8.08pm.

The British Transport Police are not releasing the exact times that the locomotive is expected travel through every town on its journey as this has led to trespassing on the tracks and other unsafe areas on previous trips.

High-speed trains take 20 minutes to travel from Didcot to Swindon but the 90-year-old locomotive will be take a little longer to get where it's going.

It could reach Swindon at around 9.35am on its way to Gloucestershire and return through the town at around 5.50pm on the way back to London.

The locomotive weighs more than 150 tonnes and uses 45lb of coal and 40 gallons of water a mile.

In 1928 it started transporting passengers between London Kings Cross and Edinburgh.

The Flying Scotsman was taken off the rails from active service in 1963 with the aim of preserving it for future generations to enjoy.

It was dismantled in 1995 before being restored by train enthusiast Dr Tony Marchington the following year at a cost of more than £750,000.
