Mobi,
A real pleasure to see you on Sunday, the Chocy is perfect. Pity that yout time was som limited.
A few points on your recent posts.
Battery Wagon, I have altered one of the cheepo LGB Opens to have a Large Packing Crate as a Load. Seams to me that Battey Kit would fit nicely inside it. You could take the Body off, drill a neat hole and run your Wires to the loco across the Balcony or at the other end.
The Box is a simple Balsa Wood Box cover in Coffee Stirers. Technology that your daughter could assist with!
Another cheep option for a Bettey Conversion would be a Newquid 2-6-2t basically a clone of the LGB Loco with the Engine Number of 99 6001. The Radio and Sound on this are poor, but at less than £100 if you look round on Ebay would make a better option to learn the trade as it were.
For RC look at Timpden RC

I have one of these systems to possibly fit out my Newquid Loco with together with a My Loco Sound set.

Looking at Screwdrivers the Maplin Set looks good, not sure about its Magnetic abilities though. You could take one of your LGB Screws in a small bag to a good DIY Shop and try various screwdrivers out for both Size and Megnetic ability. Most important that you get the Right Size as the wrong one can so easily Trash Screws.
