Chassis for the Y10 Super Sentinel

The Model Rail Y1/3 Steam Sentinel RTR loco produced by Dapol has a wonderful mechanism and I confess to having a few too many of these little locos.

While at the Warley show in November, I noticed that Model Rail were offering one of the Y1 Sentinels at a considerably reduced price, so I quickly snapped up the model. This model will provide the chassis for my Y10 super sentinel (just don’t tell the Y1 that, he’ll get upset).

Y10 Super Sentinel 3D Print

I have always had a thing for the rolling stock of the Wisbech and Upwell tramway. I have almost finished development of my BR 04 Shunter tram and I have already built both a J70 tram and Y6 tram. The one loco missing from my fleet is the Y10 Super Sentinel: A double cabbed tram that only ran on the Wisbech and Upwell for a limited time. A kit of this loco was produced by Impetus many moons ago, but you are probably more likely to find a pot of treasure at the end of a rainbow than ever see one of these Impetus kits available.

The Y10 is a relatively simple design and I had started work developing a 3D model for printing using the Blender software, but I then noticed that someone had produced a freelance OO9 version for 3D printing on the Shapeways website. To my delight there was also an ‘upscaled‘ version of the OO9 to OO gauge and I decided it was a good starting point.

The moulding is nice and rigid, and it has a wealth of detail inside the printed cab. Granted there are a few things I need to sort out. The cab doors are overly wide, but they should be easy enough to reduce down (understandable as this is a ‘blown up’ OO9 model). I also need to produce the cow catchers.

I’m really happy to finally have one of these models.

Rolling Stock – J70 0-6-0 Tram Engine

In this series of articles I will introduce the locomotives that I operate on Brewery Pit.

The Prototype
One of the main engines that see’s regular use is my J70 steam tram. The J70s were introduced to replace the ageing Y6s, and were famous for running on the Wisbech and Upwell Tramway in Cambridgshire. J70s and Y6s look very similar from the outside, but are quite different underneath the tram body. The fundamental difference is that J70s have six wheels (0-6-0), while the Y6s have four wheels (0-4-0). The side skirts are also formed in a slightly different way, with the J70s including moulded foot steps (Y6s have ladder-like steps) and a curved lower section to the skirt.

The model
My model is made from a Silver Fox resin kit that was bought for my birthday in September 2006. I opened up the side windows using a knife and added hand rails. I decided that I wanted my steam tram to include a boiler, and I just happened to have a Dapol plastic pug kit lying around (many railway modellers do, for some reason). I cut up the boiler and mounted it onto a piece of plasticard and added some hand wheels to either end. The boiler isn’t accurate as it has a saddle water tank, but I didn’t really care at the time (and still don’t).

Painting
I wanted to represent an engine running between 1948 and 1950, so I purchased as many books as possible and looked at the photos of the various steam trams and settled on No. 68217, which was one of the last steam trams to run on the line.

I weathered the boiler using weather powders and sealed it with a matt varnish.

The tram was painted with a now discontinued shade of brown from Tamiya’s acrylic range (I think it was Tamiya, I can find out if anyone really needs to know).

The final weathering job shown in the pictures is not accurate to how the model now looks, as it was repainted to better fit in with my Y6 later on.

Power
You cannot obtain a 0-6-0 chassis which would fit such a small loco, so there is little choice but to install and 0-4-0 power bogie. I was a little excited at the time I bought the kit and urgently insisted a black beetle motor bogie be sent out to me ASAP. Unfortunately, the wheelbase (distance between each wheel) of the bogie was quite wide, now I know that this is a skirted loco and little of the wheels is seen, but when it is seen it looked weird.

The motor bogie was converted to DCC control and was a poor runner and it was eventually replaced with better black beetle bogie with spoked wheels (a nice touch), a shorter wheelbase and 27:1 gearing (meaning it can travel much slower than my previous 15:1 version).

My J70 is currently waiting to have a DCC ‘stay-alive’ capacitor to be installed, but more on that some other time.
