This design, which has been through many iterations, is probably now finalized. It is to go in my workshop as a scenic test track and somewhere to play trains between jobs.

Based upon GW circa 1900 I think I have got it just about right now but if anyone can see a blooper I'd appreciate you telling me.

It's like proof reading I suppose, proofing one's own stuff is not a good idea because one 'knows' what it should be.

Seasons greetings to one and all.

Regards

Raymond

I noticed that one of the long checkrails is adjacent to the outside rail of the curve rather than adjacent to the usual inside rail.

Is there a reason for this?

Hi Bill,

Yes there is, ignorance. That's exactly the sort of thing I was hoping someone would point out. I'll change it pronto, thank you.

Regards

Hi Raymond,

Just to add to Bill's point, the same is also true of the road leading to the wagon TT in the corner. Also, I wonder why, if the Back road needs a continuous check, why would the Main not also need one?

(sorry - clicked the send button by mistake!)

Probably there are a few other places where the radius is even tighter - indeed, I worry a bit about the minimum radius which seems to be about 28 inches - are you sure even a 4 wheel wagon will cope with that?

Good Luck!

Howard.

Thanks for the comments.

The road to the wagon turntable has had the check rail removed. It was originally a sharper curve but when I printed it all out full size it was obviously wrong so I've changed it.

The full sized print out suggests that the sharp curves will work but I intend testing a little more first. Might have to alter parts of it yet again. The tightest curve is 30 inches.

Regards
Raymond

Hi Raymond.

I picked up the 28 inch minimum from the Crossover 2 point - (I think the actual min is 28.6). Perhaps it would be worth building a "rough mock-up" of the Crossover 2 point just using PCB sleepers to test how well it works and how much gauge widening might be needed?

I suppose the only way to really ease the minimum would be if you were able to come "into the room" a bit more and take the curve further into the straight part at the righthand end - but that would change things just too much perhaps.

Many thanks for sharing your .box.

Best Wishes.

Howard

Hi again

I had noticed the tight radii but assumed that you were well aware!
9 and 10 foot wheelbase wagons are good down to 30 inch reverse curves without buffer locking but I fear you may have some problems with locos.

I realise that you have spent some time on the design but wonder if the crossover and radii on the "main line" would be eased if the crossover function available in Templot were used instead of the partial templates. As Howard suggested working with a continuous curve at the front of the layout would make quite a difference - the plain track at each end need not be straight.

I do think the concept is great for such a compact setup and will certainly give you plenty of scope for "playing trains".

Best wishes

Bill Campbell.

Thanks again Bill, that is useful food for thought and I will investigate your suggestions. I probably have room to make it a continuous curve but it has to sit between my workbench and the library bookshelves on one side and the end of the bench and the window sill on the other.

Regards

Raymond

Hello Raymond,

 

It being betweenchristmasandnewyear time, I had a little play with the concept we were talking about. I think it has massively improved the min radius issues but might be completely wrong for your needs - feel free to turf it in the bin in that case! 

I altered the single slip to be "outside" which would make an interesting little construction job though it is all a bit of a tight fit!  If you like it, I hope you will enjoy all the partial templates:D

 

Best Wishes,

 

Howard.

Nice idea Howard and the outside slip looks 'interesting however, I had already decided that the whole thing needed redrawing.

So thank you all gentlemen for your invaluable help and here is the new incarnation. I do not think there is a radius less than 34" and, I feel, it 'flows' better. I even got another dock line in too.

Regards and a Happy and Prosperous New Year to one and all.

Raymond

Hello Raymond,

I think you have have moved things on well here. My only suggestion would be to move the point in the bottom left corner a bit more "round the curve" to get rid of the slight dog leg on the exit track. Are you sure you wouldn't really like an outside single slip:-)

As an alternative, you have the option now to make the single slip into a double - though that might make the shunting a bit too easy!

Looking forward to seeing it "in the flesh".

Regards,

Howard.

Hi Howard,
I think I have finally cracked it all now, there is one at 30.8", one at 34.2" and all the rest 38" or more. The turnout into the shed had to be moved anyway as there was not enough room in the head shunt to be useful. I decided that an outside slip would not have been prototypical for this track layout.

Now to start planning the base boards and one day it will appear on my website.

Regards

Raymond
