Stapleford Steam Miniature Railway will be open on Sunday and Monday for the second and last time this year as part of a steam rally supporting Loros.
Trains will depart at 10am each day. Visitors can also see vintage tractors, vehicles, traction engines, fairground organs, model railways, miniature steam engines and Punch and Judy show.
There will be craft and trade stalls, a licensed local real ale bar and hot and cold food. Admission is £5 per car.
On Sunday morning the BBC will film the railway for Inside Out, which is due to broadcast in September.
