A shelf layout to fit in the closet

We’ll be going away for a couple weeks so I thought I would finally enjoy some time just playing trains and shunting around! I am very impressed with the running (one quite clean track), only a little bit of stalling at slow speed over points. 
I’m pleased with the wiring and the track plan as well, it’s nice to have an inglenook with some flexibility on the length of sidings. 
Also got four new pieces of rolling stock (mainline wagons in front row ). Bought them on Facebook marketplace in Ontario and shipped there here..! 

Nice wagons Darius.  I wonder, are they expensive in Canada ?

Well, the problem is that it’s almost to find anything in a local store in Canada. Even in the cities I frequent (Vancouver, Calgary, and Winnipeg) the only British things they’ll have is a Hornby trainset for $300+

These wagons were $15 each plus $20 for shipping. $20 a piece or about 10gbp. How does that seem?
Thats the cheapest I’ve seen rolling stock for sale in Canada.
Generally I’ll save up a bunch of things and make one larger order a year from the UK to save on shipping. 
I may buy another loco after Christmas and was thinking to post here first and see if anyone had a spare to sell. It’s also hard to find specific things for a decent price here. Not a ton of choice!

Had a couple minutes, so I decided to break out the paint again. 
This is my first wagon… it has often looked strange to my eye, and I recently discovered it’s because it was originally designed as one of hornby’s troublesome trucks. 
Not perfect but some paint definitely improves it. 
My wife is wondering how it took my so long to get so little done…

I'm not totally up to speed on wagon prices in UK Darius - they are expensive here in France but your £10 looks slightly cheaper than in Blighty.

OO gauge stuff is also difficult to find on the Continent.  There are a few shops stocking bits but, like on your side of the pond, everything is HO.  This means I buy virtually everything from UK but since Brexit, that has become expensive so I tend not to buy unless I'm over there.

Nearly forgot - your new paint job looks the bees knees.
