I'm a bit late to the party on this one, but I've read the comments on this thread and the Lambs Leep thread and have some thoughts on the use of rtr. For me, it comes down to time. When I started building Diddington, I made a few decisions, one of which was I wanted to get something running and reasonably presentable within a relatively short space of time. One of those decisions was to use rtr when it was suitable, as I felt I didn't have the time to build everything. I think the thing is to select items that are compatible and would be seen together, not mix things up. Weathering greatly enhances models, and adds inividuality. The results, as you show, are far greater than the sum of the parts. It's also quite fun to tell people at exhibitions that everything they see on the layout can be purchased on the trade stands in the hall.
Always happy to welcome you to the party Alex.
I agree wholeheartedly with what you say. Time plays a huge part in my approach and try to maximise what little I have.
Also, it's all down to how things are presented. I've had people congratulate me on how nice an EM gauge layout Mutton is then look a tad bewildered when I explain it's PECO code 75.
For me, I am comfortable in my inability to build locos in either scale to the standard of today's RTR and why would I try when so many of the locos I would want are now available or about to emerge. The current standards are pretty high in the world of 4mm RTR and that trend is continuing into 7mm.
This also saves huge amounts of time which I then use to build layouts.
That said, I do want to try different things in 7mm. In having to go with a small (very!) layout, I should have time to spend on building things by using a basis of RTR supported by kits, scratch built buildings and kit built track.
I have no plans to add to the three 4mm layouts currently built............though the Hornby L&SWR Terriers have been released..........and the Bachmann 1P is due in a couple of months....
As ever, we shall see........
