The St Albans South Signal Box will be opening to the public for free tours during the half-term holiday.

The event will take place between 2pm and 5pm on Wednesday, October 26.

The historic location was built in 1892, and is the largest preserved signal box of its kind.

The chairman of the St Albans Signal Box Preservation Trust, Tony Furse, commented: "The Signal Box is often described as one of St Albans’ hidden gems.

"By opening during half-term week we are giving more opportunity for local families to come and see what we have on offer.

"There are a number of hands-on activities, bells to ring, levers to pull and Thomas the Tank Engine and Friends to see on our garden railway."
