RANG Railway
Willed into being by volunteers, and a joy for thousands of visitors.
A short ride onto the marsh
The volunteer-run Royal Arsenal Narrow Gauge (RANG) railway takes you from the visitor entrance towards the museum buildings. The diesel locomotive and carriages are run by volunteers. Track, platforms and the welcome at each stop are volunteer work too.
Narrow gauge means the rails sit closer together than main-line track (standard gauge is 1,435 mm). That smaller footprint suits a site hemmed in by Thames Water works and the river.
Why “RANG”?
The name is a nod to the Royal Arsenal at Woolwich, a short way up the Thames. Over centuries the Arsenal ran hundreds of trains on more than 180 miles of railway for munitions, stores and military traffic. Our engine shed sits only about 100 metres from where that Arsenal railway once ran.
RANG is not a replica of the Arsenal system. It is Crossness’s own two-foot-gauge passenger line, built so visitors can cross the site without a long walk along the works road, and so the Trust keeps a living link to how railways once served this corner of the marsh.
Railways at Crossness before RANG
When the pumping station was built in the 1860s, a contractors’ railway linked Plumstead sidings to Crossness Point. Material and people moved by horse-drawn wagons at first, then by steam. Sections of that line were lifted and re-laid more than once as the works grew. After Crossness opened, parts of the original contractor line were taken up; another railway served later rebuilds in the 1880s. The last of those site lines had largely gone by around 1940.
RANG picks up a small piece of that story: a new-build narrow-gauge railway on a short stretch of the old contractor route, rather than a museum replica of a vanished main line.
Building the line
Work began in earnest at the end of 2018. There was no contractor and no grand budget. A handful of dedicated volunteers willed a railway into being: they moved well over a hundred tons of stone, laid the track, built the stations and restored a locomotive, by hand. That force of will has since carried thousands of visitors across the marsh.
Today the line has two stations with loops. The team has landscaped around the platforms and planted a small vegetable garden by the southern stop. Platforms and gardens now welcome passengers on open days. Maintenance never really stops: ballast, sleepers, points, fencing and drainage all need regular hands-on care.
Bazalgette, the locomotive
The working diesel is a restored Severn Lamb machine, once known as Busy Basil and renamed Bazalgette after Sir Joseph Bazalgette, chief engineer of London’s main drainage and the man behind Crossness. The loco and two carriages were fully restored by the RANG team, and carry visitors on open days and many tours.
When you can ride
When it is running, RANG is part of Steaming Days, special events and guided tours: a short ride from the public entrance towards the museum. Check the event page for the day you book.

Join the RANG team
The railway is entirely volunteer-run: driving and guarding on public days, track work, painting, gardening around the stations, and keeping stock serviceable. We pride ourselves in being welcoming to both new volunteers and visitors alike! You do not need railway experience to start. Enthusiasm and a willingness to learn matter more.
