But then, that could be down to the non-availability of RTR BR/SR EMU's!
Presumably Hornby and Lima sold loads of AC OHLE locos, yet where is the readily available catenary? I wouldn't have a clue where to start looking for OHLE, but I do know where to get an AC loco in the next ten minutes...
Outside of model rail exhibitions, I've never met anyone who has a clue (or a care) about the regional availability of a loco, or whether the pantograph is up, down, or fallen off completely.....
I cross 6 tracks of SR mainline by open lattice footbridge every day, I always stand for a while and a watch a few expresses hurtling up from the distance (because I just like to see the trains run) and I couldn't honestly tell you whether there is a 3rd rail present or whether it has been ripped up by Railtrack and replaced with something more exciting. I certainly wouldn't notice the 3rd rail on a model layout. What I *would* notice is whether the front-end profiles of the EMU's look convincing....
And what does this all prove? I dunno, but I wish Hornby would forget about Pendolinos and get on with the Wessex 442, which is simply the most beautiful object on the contemporary railway, followed by the Gatex 460. Both units have a car with sufficient blank sides to stick in a decent weight over the mechanism. And then perhaps the motor would be able to drive the whole unit!
I'm quite sure that those who wanted a 3rd rail on their layout would put one there, and those who didn't, wouldn't.
