i got my old trix twin set out with it's three rail set up. bought a few used trains off ebay, lima, hornby, mainline and graham farish oo. my trix locos are showing their vintage, they run but wobble. must say how impressed i am with lima, quite easy to service too. i bought some peco set track code 100 and was surprised to find that the hornby, which ran well on the trix track didn't work so well and the mainline didn't like it much either. lima locos were fine. any comment welcome.
