Laira Tour – Laira Traction & Rolling Stock Maintenance Depot Tour with Flying Scotsman & Black Five


Hello this is Neil from Dawlish Beach
Cams and welcome to our first mini documentary. Today we will be showing you
around the Laira traction and rolling stock maintenance depot in Plymouth. Flying Scotsman was originally built in Doncaster for the London and North East
railway emerging from the works on the 24th of February 1923 and initially
numbered 1472 it was designed by Sir Nigel Gresley as part of the A1
class the most powerful locomotive used by the railway. In 1928 it was given a new type of tender with a corridor which meant that a new crew could take over
without stopping the train. This allowed it to hold the first ever non-stop London to Edinburgh service on the 1st of May reducing the journey time to
eight hours in 1934. Scotsman was clocked at 100 mile an hour on a special test run – officially the first locomotive in the UK to reach that speed. LNER passenger locomotives had always been painted apple green but during the
Second World War Flying Scotsman was repainted in wartime black in common with all railway stock. After the war it became green again and
was rebuilt as an A3 Pacific. In 1948 rail travel in Britain was nationalised with the formation of British Railways. Scotsman now numbered 60103 was
painted blue for a time and then BR green again. It remained in this colour
until 1963 when it was retired by British Rail. By this time it had
undergone several alterations to improve its performance but it had been pulling
trains for 40 years and steam engines were becoming old-fashioned. To find out more about this incredible locomotive please visit

Western Railway and mainly deals with overhauling the daily servicing of their
feet of high speed trains and also the DMU’s used on local services. After 60 years as a steam Depot, Diesel started to arrive in 1958. Later on a dedicated
diesel Depot opened in 1962 and was expanded in 1981 to accommodate the HST. Today they are busy maintaining the
black Five locomotive alongside Flying Scotsman as they prepare to head back
out on their tour. We’re gonna head into the depot now for
a walkthrough. This first HST power car is that it’s
cab removed it’s having a new sound plate fitting and wiring loom. You’ll see this a bit further in the walkthrough These are the train lifting jacks that
can lift up to 35 tons. They remove the power cars from the bogies and then this is the mule that will push the bogies along to the wheel lathe. the way lathe is used to re profile damaged wheels. This first power car on the right is the
Scotrail 7 Cities. It’s heading back to Haymarket through
Teignmouth. then through Dawlish Laira depot does not do any major work on the diesel engines. If in-house if major work is required
the engines are hoisted out through the roof of the power car and sent to the
manufacturers. A refurbished engine is then replaced back into the power car. The HST’s are just over 40 years old
and cover a large mileage on the daily basis. A typical day for HST would be
around a thousand miles. They cover roughly between 220,000 and
250,000 miles a year. this is a HST’s alternator. This large block is called a cooler group. it houses the HST radiators and they’re
checked for airflow and removed for a power wash if required. When they’re in, you got wind gun and you check the the radiator panels for panels and check the
airflow gone through. If they’re bad you can get them out power wash them. sometimes it brings them up. This is Dawlish Beach Cams Nick and he’s a marine engineer he’s comparing the HSTs layout to the ship’s he works on. As you can see with this power car the roof has been removed. From the lower level maintenance can be
carried out along the skirt. this is the main compressor for the
brakes this HST power car was struck by a tree
in Plymouth New Year’s Eve 2017. You can see there’s been a lot of damage to the fiberglass cab the driver was shaken but unhurt. This shed can fit 4, full-length HST’s
in for maintenance. from February 2019, 8 car HST’s should be replaced on the Paddington services with IET’s. Great Western Railway will retain
13, 4 car Castle Sets HST’s that will be running between South Wales and
Penzance covering local services. GWR will also keep for spare HST power cars. Brake pads are checked on every
inspection and replace frequently.
