Neptune 4 DB Locomotive running on huge portable miniature railway

We laid this railway for the Portable Railway Club www.portableminiaturerailway.com
In April 2023 the Portable Railway Club had been booked to do a very special event for Siemens at their Goole facility. This building is where all of the new Piccadilly line tube trains will be assembled, and we were asked to provide a miniature railway for a large group of primary school children as part of a scheme to encourage young people into engineering fields.
This was a sizable railway measuring around 150m complete with balloon loop, sidings and turntable. We ran both the club's DB Neptune 4 and also the Class 20 and both performed excellently.
