The B Class locomotive, built by the London, Brighton and South
Coast Railway in 1855, was a pioneer of steam power. With a 2-2-2
wheel configuration and a powerful single-expansion steam
engine, this 30-ton machine reached speeds of up to 50 mph.
Designed for both passenger and freight services, it was a critical
part of the railway's development in the mid-19th century. Though
retired by the late 1800s, its legacy lives on as a symbol of
innovation and efficiency in early railway engineering.
- 2-2-2 configuration (two leading wheels, two driving wheels, and two trailing wheels)
- Single-expansion steam engine
- Cylinders: 16" x 20" (406 mm x 508 mm)
- Driving wheels: 6 ft 1 in (1,854 mm) diameter
- Boiler pressure: 120 psi (827 kPa)
- Weight: approximately 30 tons
- Top speed: around 50 mph (80 km/h)
Information:
- Built by: LB&SCR's Brighton Works
- Year built: 1855
- Quantity built: 10 locomotives
- Purpose: Mixed-traffic duties, including passenger and freight services
- Notable features: The B Class was one of the first locomotives to use a single-expansion steam engine, which improved efficiency and power compared to earlier locomotives.
- Withdrawal: The B Class locomotives were withdrawn from service in the late 1800s, replaced by more modern designs.
Historical Context:
- The B Class was part of a series of locomotives built by the LB&SCR during the 1850s, as the railway expanded its network and services.
- The locomotives played a significant role in the development of the railway, enabling faster and more efficient transportation of passengers and goods.
