7 1/4" Bagnall
The Bagnall loco has received an extensive overhaul over the past 2 years.
This page shows pictures and descriptions of what work has been carried out to the loco.
The loco as purchased. I believe that the loco was out of service for a number of years so work began on dismantling the loco and seeing what the damage was.
Poor storage had resulted in severe water damage to several of the locos components.
The tanks, cab and boiler cladding were obviously affected but the main concern was the boiler.
The boiler removed from the chassis.
It was decided to replace the boiler with a new copper one.
Work on the chassis could begin after all the grease and oil had been removed.
An assessment of what work would be needed could then be carried out.
The cylinders before and after refurbishment, bored out to remove rust pitting and a new port face plate was fitted.
It was easier to make new crossheads rather then clean up the old ones, cast iron slippers were fitted with oil grooves to ease lubrication.
The smokebox base had all the broken studs drilled out and replaced with stainless studs and the mating faces for the steam and exhaust pipes were skimmed with new pipe unions made.
The refurbished slide bars and cross heads ready for fitting with new oil cups.
The frames after painting ready for assembly to begin.
The build was progressing well. Wheelsets in place along with the springs, side rods fitted after being refurbed and painted, cylinders back together with new cladding and stuffing glands and valve gear fitted as well.
The reverser was overhauled and fitted.
The pony truck was completely stripped down.
It had new axle box bearings fitted and a new pivot frame to allow the fire bars to be removed after steaming.
A new smokebox was rolled and welded then the chimney was added along with a new door and hinges and new dart and handles.
New water tanks were fabricated with new filler lids and vents.
Filters were added on the injector feeds and a pair of steam chest covers were machined.
The new boiler arrived and had new fittings made for it along with a new firehouse door.
The regulator quadrant would later be replaced along with the handle.
The first fitting on the frames and into the smokebox.
The new regulator quadrant was machined and fitted and new water gauges were added.
Stainless steel boiler cladding was fitted and the sanding box was fabricated.
The original cab and bunker were retained although a lot of work was needed to remove rust and dents and a new floor for the coal bunker was made from stainless to prevent rusting.
New makers plates were purchased and the final fittings were made.
Boiler cladding painted and fitted.
I decided to use Crimson Lake as the loco was originally in a similar colour.
Boiler bands were painted and lined.
The rear bunker and cylinder cladding painted and lined but this design of lining would be removed and changed
Side tanks painted and lined with the new design and bunker and cladding re painted and lined to match.

On track for the first time after testing.
