90 Glorious Years
St Ives steam and diesel
There was no mains water at Gwinear Road. There was never a water column there.
The pillar tank at Praze was provided because of this. When a shunter at Gwinear Road required water, the signalman at West box contacted Nancegollan box and a staff was withdrawn on the understanding that the engine was proceeding to Praze to take water, then not passing through the section to Nancegollan, but returning to Gwinear. This would normally be forbidden elsewhere, but special provision was made in this case, outlined in the sectional appendix to the rule book, published in 1938 and revised in 1960.
Isolated spots on the system without mains water normally had supplies provided by train in large cans (places like Largin box come to mind). I am not sure whether there was a well at Gwinear: the big house next door certainly had one.
