Portable Miniature Steam Railway and Railway Engineers

Southern Miniature Railways is a small company based in Launceston, Cornwall, which has been involved with ride on miniature railways for a number of years.

Our primary public activity is running our Portable Miniature Steam Railway at events throughout Devon and Cornwall.  A popular addition to any event, we are always interested in attending new events – so if you are organising an event and would like the railway to attend, please get in touch.

We run a fully equipped engineering workshop, able to build and repair miniature railway equipment.  Often we have refurbished, second hand and new railway equipment for sale – see the For Sale page.


In addition to our portable railway, we have a permanent 10¼” gauge railway – the Penrose Light Railway – on a private site in Cornwall.
