I'm not a frequent visitor to preserved lines, but have visited two in the last few months. And something struck me that seems obvious to me, but maybe I'm missing something.
Why don't preserved railways have a decent selection of models? I can quite easily imagine kids getting off the preserved train they've just been on, whether hauled by a GWR Pannier or a Class 37 or whatever, going to the gift shop and seeing models of that exact loco for sale.
If I was that kid, I'd be badgering my Mum & Dad like mad for the model. I reckon it'd be a gold mine!
Well, I am no expert in retailing, but
a) models cost a lot of dosh (at least, in my estimation). I have just googled 00 gauge Bulleid Pacific Hornby, and seen that new model locomotives appear to retail in the £130 160 range.
While one might not sound very much to some on decent UK salaries, buy in 15 or 20 such models, and you are tying up a lot of cash in stocks. Of course, you could get those at wholesale prices, but hey, it's still a lot of money.
b) And stock of that value needs careful stock control. If someone nicks a Thomas-the-Tank-Engine T-shirt, you lose maybe £1.00 or £1.50, Losing a Hornby Castle (or even little Johnny dropping it on the floor) and you've lost £120.00.
c) selling a model locomotive (or even a carriage) is not like selling a mug or t-shirt people start asking questions so your volunteer behind the counter needs to know some answers. you might have the right volunteer, or you might not.
d) If the Thomas T-shirt has a hole in it, even at £5, the buyer may just forget it. But if a £140 scale model of Alfred the Great doesn't negotiate the owner's points, you gonna need to be able to replace it, or somehow solve the problem.
That needs some sort of reliable after-sales service and/or more money, or you may be in trouble - legally.
Just my amrchair, amateur thoughts
. Maybe some preserved railway operations have nailed all these issues and more, and successfully sell models.
