I am trying for four tracks on the sector plate. One will have to be empty all the time for layout movements. Passenger trains will be mostly Pull Push and if save a P set with or without an extra van. Goods as I feel fit. The sector plate will need to be stored between sessions for access to the room.
I am thinking if it's worth making a treverser or a secondary sector plate a pivot end to move locos around without handling them. A small traverser is favourite I think.

That sounds good. I suppose my question boils down to “how do you get the Loco to the other end in the fiddle yard?”

That is why I want a loco length traverser on the sector plate, I will either use the storage sidings to run around or. Put one in somewhere else. I did think about cassettes but do not want be carrying around complete trains. Especially getting older might be asking for a lot of repair work.

I've done a few revisions to double slip plan. I have smoothed out a couple areas added the three way as per the other plan. Have moved the gas works a little but still not completely happy with this. Not sure what to do about it on either plan.

I am pleased with the radii I have got there seems to me only one that is under six feet. and the is into the bottom siding. which is four feet, just as well nothing with along wheel base will be going in there. All points are now 1 in 8 apart from the outer one on the three way which is 1 in 6.5 or there abouts.

The run round extension looks short. I need to check both designs it should be about 300 long. Will clear all the locos I want. I think! The LSWR locos weren't very long until you add 8 wheeled tenders.

I have stuck together the second plan. It does look some what larger than the other one. Will clear room and see how it looks in the room. SWMBO came in the room just as it was laid out. Muttered something on the lines your not having that in this house. I did point out it was going in my room. So son and I can get out her way.

Looks like it flows nicely. Always shocking for the household authorities how much room 7mm takes up. Amazing though how small domestic layouts look in an exhibition hall.

Thanks Chris. I think it will look nice with a loco and two 48 footers in the platform. And their wheels will do more than one revolution to get there. I am sticking the one with the extae loop together I want to compare both in situ.

I was concerned about the extra siding off the 3 way but I think it's ok.

Peter, what 48 footers are you thinking of building (prototype/kit/scratchbuilt)?
 

Peter Cross

I'm halfway through scratch building a gated pull push. Well I've made the trailer just need to build the driver now. I would also like some Roxey ones. But they'll have to be later I already have 6 unbuilt carriage kits.

Here's the other plan. Having both printed out. I can now start working on which one to use. I like both so it's going to be a bit hard.

I still like the idea of 3 loops as I can stop shunting and use a passenger train without clearing the run round.

Anyway what do you all think?

I will check. But I know the centre loop is longer than the sector plate. The slip I think ought to be a double. But I would prefer a single. As the inner one is very tight.

The tow truck was going Choo Choo along the tracks guided by a little hand a few minutes earlier.

Slightly O/T. One thing I’ve not cracked with simple BLT to fiddle yard designs is how to create an effective system of freight traffic simulation so there is meaning and purpose to freight train formations in and out. It’s always bugged me on Kelly Bray. The passenger service is simple, a 2 coach set, shuttling in and out with the odd tail traffic, which as it’s passenger, would be in the carriage formation book.

I think the thing is it's like the passenger service few and far between. Looking at Bodmin there was only one goods a day. Quite possibly only exchanging a few wagons. The loco then move things around as needed.
I want the gas works as that adds a load of wagons daily. Plenty of shifting them in and out of the gasworks and the storage siding. After this it is down to the delivery of what a small town needs to survive, on a probably daily basis. So maybe a couple of three wagons. Cattle once a week if there's a market.

Here's the single loop plan in the space it will be going. I'm going to chop 2-300mm off the length at the sector plate end. As is, barely give 1000 on the sector plate. I don't think it will detract at all.the positioning mean that the station building and goods shed will not be butchered. I can bring up the 3 way without altering anything. These though are just detail changes. Main thing is it fits where it's supposed to. There are some spaces for scenic development too.

Here is an overview.

Overall I like this. Fits the space with a bit of leeway. I don't think it will be boring to run,( my biggest fear). I'm not a great one for playing trains.
I will try the other one tomorrow and try to make up my mind which plan to finish.

Pedro's at school so dad has an hour to himself. Here is the plan in place with the 3 loops and double slip. Which in the end has to be a double not single. I still like this one a lot but the simplicity of the other also has a hold on my thoughts. I needed to have a play with a few wagons to get the feel of the second two loops. There's space for 8 wagons. Which is about a metre of track. I've also pull the station building away from the end mainly to move the trackwork closer to the wall. I think it is also a better relationship to the shed.
The previous observations about length of sector plate still hold fast. I think I need to be able to have more than 8 wagons in a train even if not used. And also allow for longer coaching stock and add ons.

Here's the overall shot.

Back to the Bence I have a jubilee to finish.

From the photos you have taken, I much prefer the one without the second loop. All the elements (track, buildings, scenic potential) seem to sit better together in the first option. When I saw the first option my immediate thought was that you had cracked it.

I don't know how much closer together they are but in the second two-loop option the station and goods shed seem to my eyes too close and the station layout seems to have lost some of the space and flow.

Pencarrow only has the one loop vs two+ on the real Bodmin North and I'm not worried about lack of operation as there's lots of places to move wagons around. That's just my view though and you need to be happy with building and operating... I very much doubt we'll be popping over to Brazil to have a play!

Hi Chris
I am leaning more now to the one with just the one loop. I had to look at the two loop one again in this longer format. I think it's a case with both there needs to be a reason for the goods, and having short trains is more in keeping, with the prototype. With the gas works it means I have the daily pick up, and a daily mineral.
I seriously need to lengthen the sector plate. It is just over a metre. Which will do the bear minimum I require. In reality I need a 1.3 minimum. Will mean taking some off the layout. I may alter the canopy or not have one. looking at photos, it looks like Bodmins was bigger than the one on the NCR. Wadebrigde, and Padstow's although a similar shape look smaller. It can be made so it can be replaced or added as the need requires.

Funnily I set my own minimum fiddle yard length as 1.3m. I've ended up with 1.35 which is loco and 2 coaches and, with a shorter loco, a van or two.

I did try for 3 coach trains but the longer fiddle meant I lost a chunk off the layout and I then noted that the regular services at Bodmin North were all two coach affairs.

Would be nice to have a few extra wagons in a goods train but that's not going to happen. I think the important thing is to balance fiddle yard, platform, loop and siding lengths. Think you're doing well on a tricky corner site.
