Railway Technology
A steam locomotive’s gauge glass made boiler water visible
A vertical glass in a steam locomotive’s cab made an otherwise hidden water level visible. Read the museum object as part of a safety-critical working system.
Railway Working History
Railway telltales warned workers before a low bridge arrived
Railway telltales used hanging elements to warn workers of low overhead structures. Read a 1923 patent and learn how to examine the evidence in old photographs.
Locomotive Technology
Climax locomotives brought geared drive to slow, demanding railway work
Explore the geared-locomotive idea through a preserved Climax engine, and learn which details connect its machinery to logging and industrial railway work.
Locomotive Technology
A fireless locomotive stored heat instead of carrying a fire
A fireless steam locomotive carried stored thermal energy instead of an onboard fire. Museum examples reveal why industrial railways used this unusual design.
Railway Engineering History
The Fell centre rail gave mountain trains another place to grip
The Fell railway system used horizontal wheels against a raised centre rail. Explore how that differs from a rack railway and what to look for in museum evidence.
