In my Talking Stock#15 post here I discuss the background to the three Maunsell 350HHp diesel ‘trip’ locomotives. In 1937 Maunsell ordered three six coupled 350hp diesel electric locos, built by the SR at Ashford with English Electric power units, to compare against the Z class 0-8-0 tanks. They were numbered 1,2 an d 3. These along with later revised versions ordered by Bulleid, were the ancestors of the British Railways large class of 350hp shunters that became the 08/09 class.
Many years ago I built an example of the SR 350hp shunter utilising a Golden Arrow Productions resin body mounted on a Lima chassis. The Lima chassis was the best chassis option at the time. Golden Arrow Productions have since revised the resin body to fit the far superior Bachmann Class 08 chassis, so I thought I would build another before stripping down and updating my original version.
Although 3D Printing is becoming more and more popular, I believe there is still a place for such resin kits, that are simple to handle and clean up and give a smoother finish straight from the mould.
The kit nicely captures the SR shunters including their distinctive feature of the Ashford body, when compared with the later Class 08/09, the overhang at the rear of the cab with two angled lower windows, as well as the more normal two vertical windows, giving clear visibility of the buffers and coupling area.
Following the kit instructions, the Bachmann 08 chassis requires a little modification to take account for drop in the running plate at the cab end. I also increased the width of the running plate edge with the addition of some plastic section.
The resin parts were carefully (the resin material is much softer than other plastic / £SD print materials) cleaned up to remove any flash and the windows opened up. The main body parts comprising of the body, bonnet top, radiator and radiator cowl were assembled simply using superglue. I then pre drilled the locations for the four cab door and multiple bonnet door hand rails and handles, these were then added using 0.45mm NS wire and for the bonnet door catches I used some etched brass T handles from a coach detailing fret in the spares box.
Lamp irons at each end were added using as usual Bambi staples cut and bent to shape.
Although a bonnet ladder is included within the kit, I felt this was a like coarse so I used a finer signal ladder etching.
The kit includes white metal front bottom steps which I added to the chassis and folded up some spare brass etch fret to make the middle and top steps. The two handrails for each of the front steps were again made from the NS wire.
The Bachmann 08 has two small air tanks mounted at the front of the chassis either side of the NEM coupling pocket, the SR shunters had in reality a single air tank mounted across the front. Rather than keep the 08 arrangement, to better represent the SR shunter arrangement, I cut a suitably sized white metal coach vacuum tank, again from the spares box, to fit around the coupling pocket.
If you are not using the coupling pocket then the tank can be fitted as one piece across the front.
The chassis was brush painted, whilst the body was given a dusting of the reliable rattle can Halford Plastic Primer before a top coat of their matt black. The usual HMRS transfers finish the model, she just awaits some weathering (and replacing one of the bonnet door catches that I now notice is missing). After painting I added the window glazing by cutting 20 thou clear plasticard to shape and glued in place using Deluxe Materials Glue and Glaze.
Overall this is a quick and simple project using the Golden Arrow Productions resin kit to build one of these distinctive SR three shunters, and will although a bit far from Norwood their usual stomping ground make an occasional appearance on Canute Road Quay.
