Railway modelling will never die as long as we have railways, but it will change. Undoubtedly, boomers have been the biggest generation in terms of numbers (absolute &) of modellers. Boomers also have greater disposable income in retirement than any generation that follow them will have. (observation, not criticism) There will still be modellers in the following generations, but they won't be as numerous nor affluent, manufacturers will have to adapt to this. They will have to make a model platform last longer before a revamp so the regularity and progress of new models will be a lot slower. We'll probably see a lot of the top models now hanging on for decades. I'd say we've been in a golden age of progress for model railways for the 20 years. Competition is strong, Hattons were once the only -10% box shifter and got a lot of criticism for taking business away from local model shops. Now I can name several so things are bound to be tougher. They've also made a couple of mistakes along the way too (observation, not criticism). There will probably be changes to the exhibition circuit, Warley was fairly unique in being a big venue event arranged by a single club. ModelRail Scotland is arranged by an association of many clubs so more likely to find the human resources. That may not be a bad thing, some of the small and mid-size exhibitions are better than the huge ones.
