Re: modification to shell? butchery or improvement?

On the EMD 'F' units, the steps are much finer than as represented on the model body shell. Picture in the wikipedia article if you want a look, and there will be many more pics online. https://en.wikipedia.org/wiki/EMD_F-unit ) As an alternative to 'the chop' you could first try filing or scraping ...

Re: Replacing the motor in a Dapol 14xxx engine

Before dismantling further is there still a circuit from wheels one side to wheels the other side ? A meter on ohms is the ideal test method, but a 9V battery, some wire and a 12V light bulb to create a simple test circuit will do. (Or if a DCC decoder is installed, try a reset and readdress on prog...

Re: advice required

...The room is a loft in a 1930s semi, and it is fairly horrible, too hot in the summer, too cold in the winter, and the floor is shaped like the inside of a spoon, all the walls are crooked ...

Re: Steam on Lincolnshire branchline in 1958

... The branchline is extended and DMUs are running (must have as my father worked at the Lincoln diesel shed as an electrical engineer) and Wragby’s goods traffic has increased. I just fancied at least one steam loco that wouldn’t look totally out of place... How are you getting on? (I was reminde...

Re: Two different motors in one loco!

... if it's a Frankenstein job it's a very good one, the bogie plastics seem to match! Interesting, never seen that pattern of motor bogie with a vertical can motor before. It's a matter of luck with two motor bogies taken at random: when twin motoring I tried for a reasonably matched pair (ran sim...

Re: Two different motors in one loco!

Variable scale even! My understanding is that Trix' UK OO product introductions of the 1950s were usually 3.8mm/ft - then quite common in contemporary HO - and progressively 'slid' to 4mm/ft in the 1960s. (This 'variscale' within a range was completely normal amongst European HO manufacturers.) The ...

Re: Two different motors in one loco!

That's clearly feasible from the assembly diagram, the bogie frame is the same on the trailing bogie as the powered, so with the motor and other fittings both could be powered. http://www.ttrca.co.uk/D1000%20Class%20-%202%20Rail.pdf Trix was a class act in terms of product design, the weaknesses app...

Re: Thankfully never produced

Steam was dropped from Lima's OO range because Riko (Richard Kohnstam) - which was the commissioner and distributor for their OO products - quite rapidly discovered that new liveries on diesels was the winning formula, and they made this niche their territory. Lima's tool makers consistently achieve...

Re: Two different motors in one loco!

Most of the production Trix A2's were I believe loco drive; certainly the case with the one I saw operating on 'Havil' in the 1960s (de Havilland MRC's big layout, which still exists in slightly reduced form and is operable) and of course as seen on the BBC's famous 'Blue Peter' layout. But accordin...

Re: The significance of the Stockton and Darlington Railway.

The Stephensons, George and Robert, over a relatively brief period 'put the railway together' from the best of proven techniques of the day, and the 'technological stretch' of advancing the engineering of the traction, rolling stock and the track and its supporting infrastructure. This was 'bleeding...

Re: Two different motors in one loco!

I almost bought a Trix prototype model locomotive of an A2 that had a motor drive in both the tender and on the loco. The reason for this was that as a prototype model (which was really well made) it had to be appraised and they needed to see both drive units at appraisal... OF course Roco have thi...

Re: Dcc loco issues

Like me, you might regret saying that. :wink: My view, the DCC system cost spread over that time is now nearly down to £10 a year. I have had my money's worth and more using it for hours a day, almost every day I am home. As for the accumulated £2000 spent on decoders, the few infant mortalities on...
