Hello again, I asked some advice a few months ago about my old train set that my kids had re-discovered and got some very helpful responses – so here I am again asking for more advice. I didn’t get that far with the project in the meantime but my children keep asking me about the train set so here goes… I had a very old controller, made by Meccano, which some posters advised me was probably dangerous and possibly illegal given current regs and to dump it, and I took their advice. So I don’t have a controller and I’m a bit confused between the differences between analogue/digital etc. Basically with my old controller and from my memory as a child there was the controller then two wires from that, that clipped onto two metal pegs or screws onto a piece of track, which powered the trains. (pics attached) /media/tinymce_upload/59d082c222780b4741ddd0a4b0fd368a.jpg Can you still buy such controllors? If so, do I need to buy the power plug for the controller (I think its called the transformer?) seperately and the wires to the track separately? If so I would need ControllerPower transformerWires I ask because the controller (pic attached on sale from Hornby) has no plug attachment for the power source or wires with it?

Alternatively if I went to a train model shop, would they be able to sort me out everything I need? It might be easier to do that. Finally, I’ve got lots of track, given to us by another member of the family. Can you simply add lots of track and as long as it makes an electrical ‘circuit’ the trains will run – or is that not possible? Ie you need to keep to defined track layouts for the trains to work? Sorry to bombard you with questions but its decades since I played with trains as a child so I’m a complete novice with a couple of boys who have got into trains.
