Overview of BR Class 20 Locomotives
History and Development
The British Rail Class 20 locomotive, also known as the English Electric Type 1, was introduced in 1957 and remained in production until 1968. It was designed specifically for use in freight transportation on British railways. The Class 20 was developed by English Electric in partnership with British Railways and was based on the earlier Class 15 locomotive. It was designed to replace steam in the freight transportation sector, which at the time was still heavily reliant on steam power.
The Class 20 was fitted with a 12-cylinder diesel engine which produced 1,000 horsepower, giving it the power to haul heavy freight trains over long distances. The locomotive was also equipped with a multiple working system, which allowed several to be controlled from a single cab. This made it easier for drivers to operate the locomotive and increased its efficiency.
Technical Specifications
The BR Class 20 locomotive was a Co-Co (three-axle bogie) diesel-electric locomotive with a top speed of 75 mph. It weighed 78 tonnes and measured 18.97 meters in length. It was powered by a Sulzer 12LDA28 diesel engine which produced 1,000 horsepower at 750 rpm. The locomotive was equipped with a Brush Traction DC generator and four Brush Traction DC traction motors.
The Class 20 was fitted with a vacuum brake system and a train air brake system. It had a fuel capacity of 1,400 gallons and a range of up to 800 miles. The locomotive was also fitted with a cab at each end, which allowed it to operate in either direction.
Notable Features
One of the most notable features of the Class 20 locomotive was its distinctive appearance. It was designed with a flat front and a large radiator grill which gave it a unique look. The locomotive was also fitted with a distinctive cab design, which featured a large window at the front and two smaller windows on either side.
Another notable feature of the Class 20 was its versatility. It was designed to be used in a variety of different applications, including freight transportation, passenger transportation, shunting, and yard work. This made it a popular choice among railway operators in the UK.
