Saw the thread about wheel depths and I had the same problem. Just come back to railway modelling after nearly forty years. Well 'come back' may be something of a misnomer. As I recall I tended to use my Triang layout - lovingly built by my father - more as a Scalextric set albeit with trains and as a battle ground for my Airfix OO/HO figures and tanks.
I am building a small DCC layout at the moment with the new Hornby digital stuff and quite happy with it. I did mainly for reasons of nostalgia, buy a Triang Princess loco and a Triang Jinty on EBay plus I have also managed to buy very cheaply nearly all the old rolling stock that I used to have.
At the moment most of it is either in a 'dead' siding or not on the layout. I have a question about the old rolling stock - surely that can be cheaply adapted to new wheel sets? I see that Hornby sell them.
.and no I did not try and run the old Triang Loco's on the layout with DCC! I initially had the track work set up with a DC controller but had the same problems with modern points.
Hey I am even ballasting track this time around so I must be serious.
