St Albans Signal Box Preservation Trust is a registered charity setup in 2002 to preserve a unique signal box.
The Trust was set-up by a group of residents with little or no interest in railways. It is a limited company & a charity.
Mary Webster from the charity said; "The sigbox had been listed by the council but was derelict and falling down.
"Eventually we managed to get a lease from Network Rail and various grants including the Heritage Lottery Fund.
"The sigbox was restored as a working museum (computer simulated signalling) which is open to the public twice a month in summer and once a month in winter."
The attraction also has private visits and trips from schools and cubs.
Mary adds; "We also take part in Heritage weekend, St Albans weekends and loads of other things.
"The Trust is run entirely by volunteers and we are self funding.
"We seem to be a huge hit with children as there are loads of levers to pull, bells to ring and we are also a huge hit with retired signalmen who congregate!"
Trip Advisor rates the sigbox at number 7 of 44 things to do in St Albans.
