Hi all
Thank you very much for all your commentaries and thank you very much to Angus for the example layouts. I will probably do something very similar to the 8ft x 6ft layout that you have shown. That one has a couple of circuits, space in the station for alternating trains and plenty of space for shunting.
I have been rushing this a little as I wanted to get at least one circuit and siding running for Christmas but I wasn't entirely happy with the design that I had come up with hence I posted it on here and I appreciate the feedback.
I am planning to build a baseboard that can be easily-ish to split in half to move into another room if I have to although I doubt I will actually do this. The layout will 2 x 6ft by 4ft baseboards individually framed and 4 legs for each. They will be bolted together and the electrics will have connections between both baseboards. I am an engineer with an electrical background so that will not faze me.
As for the reasons for doing this? My son who is almost 4 and is train mad. He has a wooden train set that he plays with a lot. We went away for a holiday in Devon in May this year and visited Pecorama, World of Countrylife (has a mini layout) and the Model Railway at Exmouth and we had big trouble pulling him away from the train layouts. It was from that point we decided to build a family layout for us to all enjoy. I may build a smaller separate one for my son for his Thomas trains too although that will depend if he remains interested in it.
Velotrain is right that the original layout was based on my old layout although a little larger. The 3 x circuits is what the Mrs wants on the layout. I am going to be building the baseboards and laying track and she is going to be doing some of the scenary. I'm trying to keep it to 2 x circuits with tunnels as it will keep it a little bit more realistic and easier to operate. I have seen a lot of model railways on youtube, and some of them look fantastic. I have been running a double loop layout for a couple of months that isn't pinned down on a 6ft bt 4ft board and we want to keep the loops on a larger layout.
As for train shows, I have been to train shows when I was much younger but we are regular visitors to Railways museums (Swindon & NRM York) and we have been on several preserved lines; Avon Valley Railway, South Devon Railway, West Somerset Railway, Seaton Tramway and Gwili Railway.
I know it's going to take some time to get this layout finished, probably years, but it should be fun building and tweaking it along the way.
Thanks again.
