The Milton Keynes Model Railway Society (MKMRS) exhibition weekend will take place on 15th and 16th February.
Over 30 detailed model railways will be on show at Stantonbury Leisure Centre.
A range of trade support and local organisations will be attending, with there being a miniature railway for children to ride on.
Ian Bartlett, Secretary of MKMRS, said: "We are looking forward to welcoming visitors to our show and with more than 30 layouts, wide trade support and even a miniature ride-on railway, it promises to be a really special weekend.
"Model railways are popular with people of all ages and our show is an ideal day out whether you come alone or as a family group. In fact, it might even be something different to do for Valentine’s weekend!”
An ex-London Transport Routemaster bus will operate every 30 minutes between Milton Keynes Central rail station and Stantonbury Leisure Centre.
The show opens at 10:00 on both days, closing at 17:00 on the Saturday (15/2) and 16:30 on the Sunday (16/2).
Tickets can be bought in advance via the MKMRS website or at the door (cash only). Full details of the exhibition and bus service can be found at www.mkmrs.org.uk/exhibitions.
