"W" strap rail trolley

small railway used underground. When I was working underground I improvised by making things to do my work easier,I made a railway trolley to carry logs and bricks on and the track was the "W" straps laid on the ground, I could do heaps of work by myself and do ten times the work in half the time as a team of men. I suggested they make some more trolleys and was refused and the reason given was if they started using my trolley they wouldn't go back and carry them on there shoulders if the trolley was unavailable. I also used a push bike that I modified and it was used on uneven ground. All the equipment I made was taken home when I left as I had made it at home.
