6ft way - minimum?

Hi Martin,
just a quick question re the 6 foot way? is 6 foot always the minimum?
The reason for the question can be seen in the first photo, which is a screen shot of Templot lay over on a NSL map of that section of Heaton Norris the red ringed area is where there at there closest.
The rails are set at 6 foot way centers but as can be seen there not neatly alighting with maps rail position, out of curiosity I dug out a couple of Photos of that section and came to the conclusion, unless there is a bit of a optical illusion going on, with the the photos they seem to back up the map. IE the gap is something less than a 6 foot way. I also ran the dummy vehicle which showed a sixty foot coach would not clear if something was coming up the down slow at the same time.
If the 6 foot is the bare minimum then I would have to push both running lines over a bit more to the island platform, or pull the S&T track back a bit from the down slow line.
At this point I though better ask the track expert, or experts

Cheers
Phil,

Hi Phil,

6ft is the design minimum for running lines. In the real world there has to be a tolerance on that, so it's possible you might find instances where it is an inch under. But it would be very unusual to find running lines any closer than that, and no doubt it would be on the local gang's to-do list to pull it back into line. It's more likely that the map is wrong.

For yards and sidings it is possible to find tracks closer than 6ft way. There was a previous long discussion in this topic:

https://85a.uk/templot/club/index.php?threads/less-than-6ft-between-two-yard-roads.364/

For the S&T siding in your plan, the normal minimum would be 10ft way from the running lines, but 9ft way absolute minimum is permitted where there isn't enough space for more.

cheers,

Martin.

There are quite a surprising number of locations where the 'six foot' is less than six feet. I can recall Kensal Rise Station platforms on the North London Line being closer to 5'-9" or thereabouts. With an arched bridge at one end of the platform there was nothing that could be done to ease it.

Mind, I believe the record belongs to a location on the Cumbrian Coast where I recall seeing a picture of a P.Way trolley sitting on the six foot rails of each line!

Paul,

In such situations, at least in my time, on those lines, there were bars across the droplights to stop you from sticking your head out of the window.
