Big-Big Ruston - battery change

I've mentioned previously how I fitted a double AA battery box into my Tri-ang Ruston. It works well enough, but three volts means that the loco runs a little too fast for my liking. So, I've soldered two crocodile clips onto a single C holder to take its place;


Originally the loco was designed for 4 x C cells, two pairs in series and both pairs in parallel, giving 3 volts and quite a generous run time, but modern C cells are larger than they were when this loco was designed and they don't quite fit. However, I don't need a long run time and 1.5 volts slows things down and gives me more control. And, I can always swap back to the double AA holder if I feel that way inclined.


Here's the loco with a trio of tippers, on a temporary line between the sad strawberries and the woodstore;


The track is plastic Faller Playtrain stuff, dirt cheap and durable. It has to be said, knuckle couplings are rubbish when propelling through curves on uneven track!
