For once, one that isn't a bash of a Hornby pug!

To be fair the Hornby pug is a great starting point  for the construction of many things with the possible exception of a genuine Caley pug. If it gets folk into model making then long may it continue. 

I tried chopping one up years ago. Failed really, but it is how we learn. 

I wonder why the Caley didn't build more of the 262 class, they were effective wee shunters and the crews liked the enclosed cab and sensible bunker. 

Interesting to see the lamp on the cabside. From this I gather that they were lit showing a white front and red back when positioned there? Saves a lamp I suppose, unless they were on both sides of the cab?

Hi Mikkel, 

The caley lamps could show white or green to the front, always red to the rear.  The positions of the white and green denoted the train type. I tend to fit them for   "Ordinary passenger or mixed trains".

In theory I should swap them round when the engine goes back or for different trains, but I don't know how I'd do that in practice. Caley coaches do a brass casting for the lamps but they are far too small to do in a magnetic material.

One can get RGB LEDs but whether small enough to fit in a 4 mm scale lamp I don't know (they are really three LEDs in a single package) and unless one could do something very clever one would need two, forward and rear facing. Alternatively, I suppose one could arrange fibre optic leads to the lamps from LEDs mounted inside the body of the engine. I'm not sure how one would set them, though - presumably something bespoke could be done in DCC?

It is a possibility Compound, but would need really tiny leds and incredibly thin wiring. Two leds and 7 wires in smaller than a 2mm cube is beyond my skills, it is hard enough getting single chip led in a signal lamp of about the same size. Fibre optics might work but stopping light bleed and doing something neat with them inside the cab would be a challenge.

The manufacturers of led screens do produce things down at that size but I doubt Caley lamps would be a big enough market for them and as you say DCC would be needed to switch them. 

I did manage lamps which show red or white over in 1/50 scale, doubt I could go much smaller.
