Photo Below:

32670 is a Hornby model. It represents a loco that was sold to the Kent & East Sussex Railway (Where it was re-boilered, and had a unique extended bunker, not modelled, fitted.). The loco was later, after Nationalisation, transferred to the Hayling Island Branch. It is now preserved, back on the K&ESR!.


"Stepney", No.55, is a Dapol Model.  It now (after minor modifications) represents the loco as preserved on the Bluebell Railway, where it was re-painted into LBSCR livery, but in A1X condition, vacuum braked only, with no Westinghouse air brake pump.


Link to a photo of "Fenchurch",  No.672 in a "Brighton Works" livery. (2012)  This loco has been restored to represent later A1 condition.

The Dapol (& now Hornby) model is a hybrid, with A1X sandboxes on the chassis, and an A1 length smokebox (some models have a spacer ring pre-fitted at the factory to lengthen the smokebox to A1X length.).

The models also have A1 (pre-re-build) splasher mounted sandboxes, the "vents" on the tank tops (from the A1 condensing system I believe), but no "wings" on the front of the smokebox/sandboxes on the footplate.

Most models seem to be fitted with the added Vacuum braking ejector pipe, which runs from the cab front to the smokebox, as well as a Westinghouse Air Brake pump on the eight hand cab side, but only have one brake pipe fitted, which looks more like a Vacuum brake pipe than an Air Brake pipe…

With the locos when new is a bag of parts, which can, with some modification to the base model, be used to convert the locos to other varieties.


There is a pair of pipes, which are the condensing system pipes, which run from the top of the tank fronts into the sides of the smokebox (Copper coloured on Boxhill, see the recent Model Rail article).

There is a plain (not Salter Safety Valves) boiler dome, and a set of Ross Pop type safety valves. I, would assume these are for one of the "sold on" locos...

There is a spacer ring to lengthen the smokebox to A1X length. This fits onto the smokebox front, after this has been carefully removed (the glue bond can be strong!) from the boiler. The smokebox front mounting flange is long enough to go through the ring and still locate into the boiler.

There is a set of coal rails, with a coal load moulded in. This is the simplest part to fit, as it locates into the top of the coal bunker

Fitting the A1X smokebox extension ring.

The smokebox front can be pretty well glued in place.
It needs careful persuasion to part the glue bond.
There is a small location pin on the bottom of the smokebox front, which locates into a slot in the bottom of the boiler.

When the smokebox front finally surrenders, it may well be found easier to fit the extension ring over the location flange of the smokebox front with the handrail removed.

The location pin on the smokebox front locates into the cut out in the extension ring.  The two recesses are designed to clear the handrail knobs, but may prove too shallow.

I glued the extension ring to the smokebox front, and when the glue had set hard, drilled out the handrail knob locations with a small drill, before gluing the handrail back in place.

(The first attempt I made, without drilling the holes out a bit, the handrail knobs pushed the extension ring away from the smokebox front!)

It will be noted that there is now no positive location pin to align the smokebox front onto the boiler!
This is where care and attention will be needed when gluing the smokebox front to the boiler, to get the hinge vertical…

If you are going to remove the splasher sandboxes, do not glue the smokebox front into place yet!

Speaking of “vertical”, the lower handle on the smokebox door should point vertically Down, as this is the catch handle. The model comes with this handle at the “twenty-five to “ position!
I carefully carved the handle away from the bottom, meeting with a cut across the top at the centre boss.
I then re-glued the removed section in the correct place!

I have removed the weight from the boiler (held in by a screw from underneath)  and made a hole from the boiler to the motor area by chain drilling around the inside of the boiler from the smokebox end.
This makes an access to the boiler from the motor area when the smokebox front is re-attached.
I have not yet reattached the smokebox front; it is at present just slotted into place.
I have yet to fit a DCC chip, and may need access!

Removing the A1 splasher mounted sandboxes.

The front splasher sandboxes need to be removed.  This is not so easy, as the earlier Model Rail article found.

I worked out that there are a couple of places where it is not so dangerous to cut with a fine razor saw.

Cut 1 is across the diagonal from the end of the splasher, to the side of the smokebox saddle, horizontally to form the base line.

Cut 2 is again a diagonal cut, but vertically downwards to meet cut 1, across the corner of the sandbox top.

Cut 3 is across the remaining sandbox part, just above the top of the splasher, until just before the smokebox.

The top flap thus made can be prised up with a small screwdriver (or similar), and then cut off with a sharp modelling knife.

The remaining sections of sandbox then need to be carefully trimmed away, hopefully leaving the splasher side intact, and a squared off vertical flat smokebox saddle.

There should be a rectangular hole. About half is in the footplate, and half in the front part of the splasher top.

The first repair section I applied was a piece of plastic card, running from the rear of the splasher hole, to the position of the front of the smokebox extension ring, where it meets the smokebox front (This bing plugged loosely into place to get the measurement.)

The height of this plastic section should be the same as the smokebox saddle.

The real smokebox saddle has a distinct concave curve to it.

This could be ignored, or fiddly job  made to get it right (I do not think it worth while, as the splasher and clack valve pipes would also need attention, as both are joined to the boiler!)

I used round files, and put a groove into the vertical smokebox saddle side…better than nothing?

Patching the holes!...

The hole in the footplate is patched from the inside with a piece of plastic card. Making sure that it does not obstruct the wheels…
The hole now left, in the splasher, is patched with a pre-curved section of plastic card.
If required, careful application of filler may fill any gaps…

I was lucky, and managed to retain the splasher lining.

Check photos, but most A1X locos did not retain the tank top vents, in ront of the tank filler caps.

These have locating pegs that protude into the tank tank tops inside the body. In my case, using a flat item, such as the handle of a craft khife or screwdriver, I simply pushed them out from inside, breaking the glue bond.

The holes were patched with plastic card squares on the inside, and plastic rod in the hole, with glue as filler.  You may find some plastic sprue or rod of the correct daimeter, which could be glued into the holes, and then trimmed off flush with the tank tops. Or make small circular "blanks" to attach over the holes, like the real thing!

The prominent lubricator bowls for the cylinders have been represented with brass handrail knobs, inserted into holes drilled into the smokebox saddle.

I will be fitting these to the other (BR) Terrier, which represents KESR No. 3; BR 32670, which had an A1X boiler fitted by the K&ESR, but retained the tank vents, and splasher mounted sandboxes. (It does have a unique bunker extension though!)

On these A1 sandboxes, the lubricators are mounted on the front, nearest the smokebox. On A1s the lubricators are in the same place, on the smokebox wing plates.

Vacuum, Air or both forms of braking?

From photos, Stepney has had the Westinghouse air braking system removed. . (By BR I believe...)




This loco is preserved in A1X (Re-built) condition, with extension "coal rails" on the bunker, but in Stroudley livery.
The Westinghouse Air Brake system and pump has been removed, therefore this loco should only have vacuum pipes on the buffer beams, and the Vacuum ejector pipe on the Left Hand side of the boiler.

Dapol and Hornby models seem to all come with this pipe fitted. It is the plastic pipe that runs from the front of the cab to the smokebox. The vacuum brake control would be mounted on the rear of the cab front where the pipe joins the cab.

The Westinghouse pump also seems to be a standard fitting, on the right hand cab side.

On Vacuum only braked locos, this needs removing. (It is best to see a photo of  the real version of your loco to check!)
This is held on by two pins in two holes, and can be carefully prised to break the glue bond.
The holes then need plugging.

Colour matching touch up paint may be a small problem….






Brighton Works, No. 32635

Brighton Works, No. 32635, in the September 1962 photo (Earlier Model Rail article, and on the web.), was dual braked, and retained the Westinghouse pump.



There is a photo of the Westinghouse pump side on this site...which is of more Brighton interest!


This loco also has both Air and Vacuum brake hoses on each buffer beam.

The standard fitted brake pipes most closely, in my opinion, resemble Vacuum brake pipes.

I fitted two new brake pipes from a batch of spare parts. I think they may be Dapol parts
These, being smaller, make very good Air Brake pipes.






Couplings and DC fitting.

Kadee couplings, or NEM sockets, are still to be fitted.

DCC is still to be fitted.

DCC is still to be fitted.
