I have an assortment of Triang locos, track and rolling stock from the '50s and '60s that has been in boxes for the better part of 50 years. When COVID happened back in March and my regular routine came to a halt, I decided to pull out some of this old stuff to see if anything still worked. Amazingly, all six locos and the two P.5.C controllers still work. I did some maintenance and cleaning on the locos (which my brother and I had never done when we ran a layout as kids) and set up a small test track. That was all back in the Spring; when Summer came along, I got busy with other things and the train stuff went back on the back burner. Now with winter setting in, I'm looking to getting back into it and setting up a small 4' x 8' layout. My dilemma at this point is that the track I have is mixture of ancient Triang Series 3 and Super 4 track. Some of the Series 3 long pieces are quite twisted (as one might expect), while the Super 4 stuff is in fairly good shape. But it's all steel rail, which I understand is inferior to the more modern nickel silver. So - long story short - I'm looking for advice on what type of track might be compatible with my old-time equipment, whose wheels I suspect have deeper flanges than is currently the norm. Anyone have any experience running this old stuff? What should I be looking for in new track? Any advice - other than "scrap the whole lot and mortgage the house to buy all new!" - would be appreciated!
