Thanks Steve and Paul.
Bram, Whatlep and Paul from the G Scale Society are coming for a pla .......... errr ........ intensive test session next Monday (2 O'clock kick off if anyone else i able to get over to Bewdley BTW), so I thought I'd better get me finger out and build the storage sidings. This is also the last bit of track laying that is currently planned.
The hard part was getting the 1st slab (4 x 2' slabs making a 2' x8' area) correctly lined up with Stumpy Junction. After that, all the rest just had to be laid to the same level.
The standard maximum train length on the WGLR is 4 x 4 wheeled wagons plus a brake van, 4 x 4 wheeled coaches, 2 x bogie coaches or any such combo. This length of train fits into sidings one and two. I even managed to dig out a RH point which I'd forgotten I had and this allowed me to add a kick-back siding ideal for the track cleaner ........ or maybe even a steam-up bay

.
The piece of slab underneath is just being stored. You might also have noticed the cutting edge remote control apparatus for operating the Piko point at Stumpy Junc................ ie, a long stick

.
Only job that remains is to fit isolation switches to each siding. Having bought a car full of second hand track off IanS for this project, I certainly ain't got much left!!
