It's a private 7 1/4” gauge miniature ‘Standard Gauge’ railway. It is based mainly on the LMS  and early LM Region of British Railways but is home to models from any other railway or era.Train Club

Open every Bank Holiday to visitors. Gates open at 11:00am.
It's a great couple of hours out for all the family, whatever age.  Ride the miniature trains, they have two circuits, including a tunnel for the adventurous.  Kids from 5 to 105 can enjoy the ride and feel the wind in their hair.
Refreshments are available and they have seating to sit and watch the trains go by whilst enjoying your picnic.
Located just off Jnc. 2 of the M180 they're just 30 minutes from Doncaster and it's well worth the run out, whatever the weather.  They're just down the road from the Sandtoft Transport Museum so why not make it a full day out and visit both.  They have ample free parking on site.
Their website is at for location details, a track plan and some great pictures.
