Re: Changing wheels on Triang coach

Are these the kind of old wheels that had axles with rounded rather than pointy ends, that actually stuck out through the axle box? I fixed up a few of these by tapping the axle box holes M3, slicing off bits of M3 bolt to about 3 or 4 mm long, popping dents in the end of the bit of bolt with a smal...

Re: Cliches of Layouts or Model Railways that you dislike.

Ok, to briefly return to the original idea of the thread, how about - scenes set in a particular decade that have a surfeit of the express engines that were brand new that decade, but far too few humbler older ones. Steam engines often lasted a long time and there should be masses of creaky old frei...

Re: Cooper Craft Parkside Dundas Kits.

I did a Parkside Dundas private owner coal wagon recently as my first-ever kit. I meant to post about it here, but I can't find my blasted camera charger anywhere! It needed fairly careful cleaning up along the casting seams but then went together easily and looks good (well, I've not finished paint...

Re: Power for Expo turntable motor from a controller

I second Flashbang's suggestion of using a voltage regulator instead of a train controller. The resistor approach is not really sufficient to give you a stable voltage when you turn the motor on, so what you think is OK, might not be. Also, it will get hot (you'd need one rated for more watts than s...

Re: Hornby train packs - are they value?

Erm, isn't Railcom someone else's proprietary system? In which case it's not bizarre - it's quite sensible for Hornby to be a bit wary about adopting it, especially as a "Railcom plus" is already being advertised... I think they have a massive amount of work to do if they want to survive, ...

Sadly I don't think I'm free then, but I didn't know about Keen House and the MRC either, so thanks for that.

Re: Safely combining DC and DCC?

Pete - thanks VERY much for telling me that the scheme I am looking for is "cab control". I am tolerably familiar with electronics but not with doing model railways properly, so didn't know the term. Looking it up, cab control is the correct name for what I have been trying to do anyway, a...

Re: Safely combining DC and DCC?

Gordon - ooh, thank you for the suggestion, I will definitely have a look at MERG. Also, very good point as to whether I would need multiple detectors. If I did, it would be a complete nuisance and - as you say - not necessarily viable. Will have to have a think about that, though I had hoped I woul...

Re: Safely combining DC and DCC?

Ray, I like your thinking and I can see what you're getting at. The main problem, I think, will be decoder fitted locos. In the absence of a DCC signal, the decoders revert to DC mode. Your test signal will just get passed straight on to the motors. Hi Major, sorry, didn't see your reply before I p...

Re: Safely combining DC and DCC?

Thanks for your input, chaps, but I'm afraid that maybe I didn't explain very well. I know DC is DC and DCC is AC and why it's not safe to put AC across a DC motor. However, my original idea was that it should in theory be really quite easy to build a circuit that detects whether there are any DC mo...

Safely combining DC and DCC?

Hi all I'm having a go at railway modelling for the first time since I was a kid (well, no, you guys are railway modelling. I'm just playing with toy trains :D ) and I'm fairly electronically inclined, so I'm building my own DC controls. I'm intrigued by this DCC computer control business but, at th...

Re: Narrow couplings

Thanks for the link. Looks like the engine is Hornby's "Narrow" style. They seem cheap enough to get some to play with, and they certainly do work with the old wide style, so I wouldn't have to change everything at once and it wouldn't be a disaster if they turn out to be a bad idea on tig...

Narrow couplings

Hi everyone, Returning to model trains after a long time - I've recently acquired a Hornby Flying Scot (just the trainset version, not a fancy super-expensive one) and was surprised to see that it has a rather elegant narrow coupling on the rear of the tender instead of the traditional huge D-shaped...
