One problem we face at TGBMRS, was the lack of electricity. There was a power point in the floor, but just the other side of an escalator. It didn't seem sensible to run a cable accross this, so initially, it looked like there would be no movement on the stand.
Then, an idea. 009 locos don't need much power, so could a 6V jelly call from a model boat do the job?
With nothing to lose, I charged up a small battery and took it along. After a testing the various locos, my "Tin Turtle" seemed happiest on the available juice, so it performed during the show.
The little loco ran happily from 9:30 opening, to about 3:30 both days. I did recharge on Saturday night of course.
A rough calculation tells me it covered a real mile each day - showing how reliable the Tomytec chassis under the Meridian Models body is. OK, speed was a little high, but you can't have everything.
Another battery, this time a 9V PP3 powered the LEDs in the car dealership. Hardly fresh when I first plugged it in on Saturday, the lights stayed on until the end of Sunday, including overnight as I forgot to turn them off!
