The front water tank would be filled to the brim, but the oil tank in the back bunker would by this time be half empty (and not re-filled until the end of the day). So, the front end would plod away quite happily but the back end would be slipping hopelessly due to lack of adhesive weight. Using the sanders didn't make much difference as they are on the front engine, and once its ten wheels had passed over the sand there wasn't much left on the railhead.
And then the steel oil tanks were replaced by much smaller and lighter plastic tanks, so it happened on the first trip as well...
Booked for, I think, 15 minutes, my record was 54 minutes to do the journey. Happy days!
If I recall, didn't the NGG16'S also have gravity sanders back then?
