Once again after the winter layoff restarting the railway is taking time end effort. It's no good trying to hands and knees the track with a bit of abrasive, neither the shape of the layout with its hanging trains, nor the shape of my body makes this anything other than an exhausting chore. So it is maybe time to splash out on a self powered track cleaner. I can't afford anything very expensive, it has to stay within a tight budget. Any ideas out there? Is there a second hand market?
