I bought a couple of Red Rocket sets when they came out. They were about half the price of the real thing. Unlike the track in the box in the photo above, all the track was black. Later I discovered that it lasted much longer outside than the official Rovex red track which became white and brittle in the Sydney sun. The engine itself seemed to be more fragile than the original.
I had a few yellow trucks but painted some of them matt black to resemble dirty NSWGR ‘S” trucks.
