Chronicling the development of my Cambrian and Narrow Gauge 4mm scale model railway


The little grey cells

As I said in an earlier post, my modelling appears to have currently reached a temporary hiatus. There is little I can do about it. I have two sons who are hardly independent, a job that has gone into overdrive, and, as my previous but one post said, I am getting to grips with the new pump world.

One of my regular readers, who happens to write a blog about modelling that does happen, said to me recently, “You like to have several projects on the go at once don’t you?” He may well be right, but I think my blog is misleading because I haven’t anywhere near as many projects actually on the go as I make out. Many have reached the drawing board and are no further.

This doesn’t concern me greatly, because the day will come when the kids are busy doing homework, and when not doing homework, chasing girls, and I will get some time to build things. All I am doing now is the planning.

Although I don’t get much modelling time, what I do get are 10 minute breaks between jobs in the office, and a lunch break where I need to think about anything but High Speed Rail in Canada, buying trains for Mexico, looking at recently scrapped trains in Australia, and has the right team won the latest franchises in the North of England (to give an example based on this week just endeth).

These 10 minute breaks are ideal for research. So for the last couple of weeks I have been resurrecting an idea I’ve had for some time to build a 1988 built steam loco in 009, and the last couple of days in amongst the hectic world of modern day Colonial railways, examining GWR tenders, Hawksworth ones in particular, both for my Pacific project and also for something else. These dabbles in online research keep the creative juices flowing and ensure I don’t end up in the loony bin.

More on 1988 steam locomotives and Hawksworth tenders another time. I may also do a piece on Hawksworth himself. The more I look into his work, the more I’m saddened he didn’t get a chance to show what he was really capable of.

One of the results of this week’s research: Did you know that Charles Collett did an 8 wheel version of his standard 6 wheel 4000 gallon tender?  No I didn’t either. He only did one. I presume it was an experiment to see if you could get the same capacity on a wider route availability. Presumably it wasn’t worth the bother.

Anyway, here it is attached to a Hall.

Fleet Guide – No.1: The Class 69

I thought it would be good occasionally to write short posts about some of the stock to run on the railway, as a fleet guide that can be built up over time into a full Traction Recognition.

Each post will have a short description of the locomotive class, or locomotive, in question. To get the ball rolling, here is the less well-known history of the Class 69.

The history of the Class 69

With the growing demand for rail freight in the UK, several years ago the Rail Freight Strategy Group got together and brainstormed ideas to alleviate capacity on the railways. One suggestion put forward for freight trains was to lengthen them, thus reducing the paths required (although it was acknowledged that some loops were of insufficient length for this plan). In terms of moving products such as coal or minerals/aggregate this seemed a good idea. However, the need for a locomotive which could haul a coal train of 100 wagons from a standing start up the 1:37 of the Lickey incline meant that matters were put on hold.

It might have all ended there had it not been for an entrepreneurial individual who had been following the flourishing of railways in Europe and the UK and saw an opportunity. Understanding something of locomotives they knew that the best type of locomotives for starting a load (i.e. greatest tractive effort at start) were steam locos, and this may be a possibility as outright high speed wasn’t the issue (as long as the loco could get the train up to 70mph-ish then all would be well).

Early research soon dismissed the idea of hybrid traction, something that had been tried by Kitson back in 1924-1935 and hadn’t worked sufficiently well – and had pretty much bankrupted the company.

The final design that was put forward was a 2-6-2+2-6-2 Garratt which could burn either oil or pulverised coal, the latter being the preference as there is a large quantity of it shipped to the UK every day to fire the power stations, the transport of which being highlighted as a use of the locomotives. Automated operation included the introduction of two regulators, one for each power unit, controlled with a WSP system, thus curing the Garratt’s Achilles heel. This coupled with high levels of remote condition monitoring meant that the design would only require single man operation and the central cab where the firebox was only needed to be accessed in emergency. Instead full front cabs were installed at either end, styled like those on the Class 66s, making the design a cab-forward Garratt.

Initially one demonstrator was built and loaned to Direct Rail Services (DRS). It was named Janus, in recognition that the locomotive literally had two faces (in Thomas the Tank Engine world terms) and looked to the past and the future, just like the Roman god.

While DRS trials were continuing, three more demonstrators were completed and were loaned to DB Schenker, Freightliner, and GB Railfreight (GBRf) respectively.

DRS saw the potential in the locomotive and negotiated the purchase of 69 001 and placed an order for a further three, continuing the naming theme started with Janus.

While the DRS additional 3 were in production, the other three freight operators decided they didn’t agree with DRS and returned their demonstrators. These were then shipped to mainland Europe to be loaned to various freight operators, and the last news was that one was to be re-gauged for trials in Russia, and one was being shipped to China.

The fleet therefore stands at seven, these being:

69 001                 DRS Janus

69 002                 Originally DB Schenker now being re-gauged for Russia

69 003                 Originally Freightliner now in Europe

69 004                 Originally GBRf now in transit to China

69 005                 DRS Belinus

69 006                 DRS Aditi

69 007                 DRS Heimdallr
