6024 Bits & Pieces

Close Window

Hopefully these shots will be interesting to those of you who like to see something a bit more technical than an action shot. Being a member of the 6024 working party has allowed me the privilege of getting shots the general enthusiast can't.

Cab

A photograph in the cab showing the drivers side and the position of the drivers air brake valve. Also prominent is the reversor, the AWS bell, the AWS horn (green and to the left to the brake valve) and the lubrication indicator.

A view of the cab with the tender and engine split during maintenance. Many cab control are visible as are the air brake hoses linking the engine and tender.To the right of the air hoses under the injector water feed hoses is the AWS pickup.

Tender

The front of the tender whilst split from the engine. Visible are the air brake hoses, the tender to engine buffer springs (out of their normal position), the injector water valves, the hand brake (right hand side), the water scoop control (left hand side), the tool boxes and top right is the tender filler often used on the mainline and essential when under the wires.

Boiler, Firebox, Smokebox and Superheaters

With the life expired smokebox ring and door removed for replacement an interesting view of the smokebox is had. The pipe work to the front takes superheated steam to the centre valve chest. The fitting of the second stage of the spark arresting cages is also shown sitting on top to the blast pipes, around the petticoat base and below the chimney. On the right hand side running plate the large brass item is a removed cylinder pressure relief valve.

To meet the Railtrack spark arresting regulations 6024 has a 2 stage system in the smokebox. This shows the first stage screen whilst out of the loco. It normally slopes down from under the superheater header towards the front of the smokebox. Behind it, on the floor, are some of the screens used in the ashpans to prevent ash falling on to the track.

The second stage in the smokebox is made up of these traditional style Swindon cages that fit around the tops of the blast pipes and bottom of the petticoat.

Chassis, Cylinders, Wheels & Motion

During maintenance these interesting shots of the cylinder minus both piston and valve were obtained. On the left the cylinder is seen minus piston. The oil is coming from the lubrication feed hole. the lubrication having been checked. Note how the cylinder end cover is shaped to aid steam inlet and exhaust. The centre hole in the end cover is for the piston rod whilst the hole to the left is for the pressure relief valve. On the right the valve is removed. Working inwards are the exhaust ports (the loco is inside admission), the inlet ports, the steam chest, then the opposite inlet port and exhaust port. Also visible is the end of the rocker arm that connects to the valve stem and thus controls the valve events.

A slightly wider shot again showing the ports and steam chest. Top right is the exhaust passage and bottom right is one of the snifting valves.

Three of the the four sets of valves out for maintenance. Valve events are ring, not head, controlled. The rings are of the Semi-Plug type as imported to the UK from the USA by Churchward in the early 20th Century.

Steve Underhill checks the bearing surface on the very characteristic outside axlebox of the leading bogie axle. It's not often you see the brass cover off ! Below the axle the pad, oil reservoir and filling point can be seen.
