Whether they were H0 or near-H0 or nowhere-near-H0 is irrelevant. They were still 'underscale' by 00 standards. They were also - as a rule - 'modern image' which was another cardinal sin at the time they were marketed.

Don't forget the AL1 Bo-Bo electric - streets ahead of the HD and Tri-ang offerings (which were essentially the same bodyshell with different chassis!).
I used to have some Trix Mk1 coaches (the buffet car in particular was a nice model) which I too found easy to convert to tension lock in order to run them with my Hornby and Lima locos; Commonwealth bogies, too, as a change from the BR1 norm. Shame about the size discrepancy, though.

Lima wheels and many older 00 UK RTR models use a back to back less than the often quoted 14.5mm. 14.3mm is the minimum for NEM H0 back to back, 14.38mm is the minimum for NMRA H0. With Martins 00-SF standard you can use wheels with a minimum back to back of around 14.3mm for 30" curves. My H0 fine scale standard tolerates a minimum back to back of around 14.35mm for 30" curves. Martins 00-SF check gauge is 15.15mm, the same minimum limit as the Australian Model Railway uses for their H0 standard. My fine scale H0 standard uses a minimum check gauge of
15.2mm, the same as the H0 NEM. Older UK RTR tends to use a smaller check gauge compared to allot of H0. You can get gauges close to my standard fromTerry Flynn
