Yep, know the situation all too well...lol, the kids don't seem to hold interest for long these days,which is such a shame, too many other distractions,playstation, Xbox, etc etc, to name but a few. The amount of times I've been left with unwanted baseboards, items of stock, track, etc, is unbelievable....3 times to date I think, but I've always believed in at least giving them the opportunity to try the hobby, after all..... 'new blood' an all that.
I initially started out with a small idea for a layout after getting back into the model railway scene in 2002, but by this time my son had also decided that for Christmas that year, he wanted a model train too.....from then on things just went to the wall, all that time, effort,not to mention the expense,...and then being left with all that model railway equipment, there wasn;t any real incentive to sell either,as the value of second hand items back then was pretty poor from most dealers.and is still pretty much the case I believe. unless you're really lucky.....this was well before I knew about Ebay of course, and how to use it. I'm now off in a completely new direction to what I'd intended, just to try and put to use all the expensive settrack curves,points etc...before you know it your buying this and that item, and that loco and really ending up way out your depth......But, I was only gonna build a little station terminus and goods yard with a few items of rolling stock,....what happened to that!!!
Looks like your taking the right steps anyway, an staying on 'Track' with your new ideas, should have done that Myself. But now I've sold my old layout 'Badgers Lane' and I seem,... after such along haul to be back on track, and have a couple of ideas which have been properly planned this time, and in process of construction...well, sort of lol. Seem to have ended up with way more stuff than I will ever need, or have time to use, seems we are all guilty of that one. Trouble is, always seem to have loads of ideas, but never enough time and space.... thens theres money, never enough of that though either, looking forward to seeing your new ideas and progress. Please excuse me for waffling on and on.... but I'm new on here, and still getting to grips with all the conversations and topics/blogs etc , think I'm doing this right anyway.lol, tell me if I'm on thr wrong wavelength.
