Brockham Locomotives: A History of Industrial Narrow Gauge Preservation
The history of industrial narrow gauge railways in Britain is a testament to the ingenuity of specialized transport. For decades, the Brockham Railway Museum served as a vital sanctuary for these machines, preserving locomotives that once powered quarries, brickworks, and sewage plants. Many of these engines were saved by a dedicated group of enthusiasts during a period when industrial narrow gauge lines were rapidly disappearing from the British landscape.
Because many of these locomotives were privately owned by museum members, the collection was dynamic. Engines frequently moved between Brockham and other preservation sites as they were restored, sold, or stored, creating a complex web of heritage movement across the UK.
Key Facts
- Diverse Gauges: The collection featured a wide variety of track widths, ranging from 1 ft 10 in (559 mm) to 3 ft 2 + 1⁄4 in (972 mm).
- Propulsion Types: Locomotives included steam (T for Tank, ST for Saddle Tank), diesel mechanical (DM), petrol mechanical (PM), and battery electric (BE).
- Industrial Origins: Engines originated from diverse sectors, including the Dorking Greystone Lime works, Guinness Brewery, and the War Department Light Railways.
- Notable Builders: Key manufacturers represented include Motor Rail, Ruston & Hornsby, Orenstein & Koppel, and W.G. Bagnall.
The Core Collection and Technical Specifications
The locomotives at Brockham represented a cross-section of industrial engineering. From the heavy-duty steam engines used in lime works to the agile diesel units used in brickworks, each machine was designed for a specific environmental challenge.
Steam and Early Industrial Power
Some of the most significant pieces included the Townsend Hook, an 1880 Fletcher Jennings 0-4-0 Tank engine, and the Scaldwell, a 1913 Peckett & Sons 0-6-0 Saddle Tank. The 23, built in 1920 by Wm. Spence & Son for the Guinness Brewery in Dublin, was particularly unique, featuring a hoist and a standard gauge converter bogie designed by Samuel Geoghegan.
Diesel and Petrol Transitions
As industry modernized, diesel mechanical (DM) and petrol mechanical (PM) locomotives became the standard. The collection featured numerous Motor Rail and Ruston & Hornsby units. For example, locomotive 166024 (1933) served the Colne Valley Water Co, while the Major (1937) was a staple of the Dorking Greystone Lime operations.
Specialized Utility Vehicles
The museum also housed Wickham trolleys, such as WD904, which were often used for maintenance and inspection. These 2w-2 PM (two-wheel petrol mechanical) vehicles provided a lightweight alternative to full-sized locomotives.

| The Major | Orenstein & Koppel | 1937 | 4w DM | 2 ft | Dorking Greystone Lime |
The Legacy of Private Preservation
Many locomotives passed through Brockham as part of private collections. This led to a high turnover of stock, with many engines eventually moving to sites like Gloddfa Ganol, the Amberley Chalk Pits Museum, and the Moseley Railway Trust.
Notable examples of this movement include Kathleen (an 1877 De Winton), which eventually moved to the Vale of Rheidol Railway museum, and LM11, the oldest surviving Bord na Móna locomotive, which found its way to the Cavan and Leitrim Railway.
Frequently Asked Questions
What does '4w DM' mean in the locomotive descriptions?
4w DM stands for a four-wheeled diesel mechanical locomotive, indicating both the number of wheels and the type of engine and transmission used.
What was the purpose of the 'standard gauge converter bogie' on locomotive 23?
The converter bogie allowed the narrow gauge locomotive to operate on standard gauge tracks, providing flexibility for transport and operation between different rail systems.
Why did so many locomotives move from Brockham to Gloddfa Ganol?
Many locomotives were privately owned by members of the museum. As ownership changed or restoration needs evolved, these owners moved their engines to different sites, including Gloddfa Ganol, for storage or work.
Which locomotives were used by the War Department Light Railways?
Locomotives such as No. 15 (Motor Rail, 1918) and LR3101 (Motor Rail, 1918) were originally operated by the War Department Light Railways.
What happened to the locomotive 166015?
Locomotive 166015 was the victim of a theft in April 1969, during which its underframe and engine were stolen, leading to the vehicle being written off.
