Whilst I find the era system helpful when perusing a catalogue I always use an enthusiast website for detailed information. I only model UK SR and there are a number of sites which give details of all locos and coaches from year of build to scrap, I would assume that other regions have similar enthusiasts who publish such information.
I realise that I have only recently returned to the hobby after a long absence but I have been pleasantly surprised by the standard of RTR models produced and feel that both Hornby & Bachmann do a v.g. job.
