James Posted November 7, 2012 Share Posted November 7, 2012 This might be of interest to a few. At work noticed just after I had come on duty that the Facing Point Lock cover was lying on the ballast shoulder. Reported Control and I went to move the cover to a safer place. (Incidentally when I was on p-way we were told you never touched any FPL equipment!) Going out to see it revealed the workings normally contained within, now recorded for you to see And an overall view - Link to post Share on other sites More sharing options...
LNERGE Posted November 7, 2012 Share Posted November 7, 2012 Shame the gauge is not 1435mm<g> Super pictures thank you. Link to post Share on other sites More sharing options...
Pugsley Posted November 7, 2012 Share Posted November 7, 2012 Yes, thanks for posting those. They're very useful for people who have to add stretchers to some FB points in the not so distant future! Link to post Share on other sites More sharing options...
buffalo Posted November 7, 2012 Share Posted November 7, 2012 Could you please explain what the rod in the 4ft that disappears towards the right in last picture is for? It appears to be linked to the first tie bar via the crank, a kinky bar and and bracket (painted blue), but where does the other end go? Nick Link to post Share on other sites More sharing options...
LNERGE Posted November 7, 2012 Share Posted November 7, 2012 This is the backdrive to ensure the free wheel clearance is maintained further along the switch rail. Link to post Share on other sites More sharing options...

This is the backdrive to ensure the free wheel clearance is maintained further along the switch rail. This was taken by a friend of mine, the turnout is the one which diverges from the mainline to the branch going away from the camera. The guy by the box was part of a gang cutting trees back (his chain saw is on th walking route!) - I normally have at least on window open but they'rfe all closed as I could hear the bells for their tools! 66603 6Z83 Gilbo by 6Y99, on Flickr Link to post Share on other sites More sharing options...

buffalo Posted November 7, 2012 Share Posted November 7, 2012 Thanks, James. I thought that might be what LNERGE meant So, if I've got it right, that rod relays the drive down to another tie bar further along the switch rails? Also seen on the turnout at the bottom of the picture? Nick Link to post Share on other sites More sharing options...

Nick The backdrive drives another stretcher bar (or bars on long switches) and can be mounted either in the four foot as in the pic below or on the sleeper ends Link to post Share on other sites More sharing options...
micknich2003 Posted November 8, 2012 Share Posted November 8, 2012 A couple of pictures of the "Back Drives" on a set of clamp lock points. As been pointed out many times, point switches have STRETCHER BARS a tiebar is a completly different animal. Mick. Link to post Share on other sites More sharing options...

Mick. Thanks, Mike and Mick. I've already written out 100 times "I must not call a stretcher bar a tiebar".

RMweb Premium Gary H Posted November 23, 2012 RMweb Premium Share Posted November 23, 2012 Its also worthy of mention that the side the point number is fitted to is the normal side, ie, it denotes which position is normal. Its not always 'easily' obvious! So in James' first picture, those points are in the reverse position. The arrow next to the points number is unusual though, rare to see in my experiance and again it just points to the normal side. If the number ends in either 'A' or 'B', it will be part of a cross-over, "The A end or B end". Likewise, a catch point may also be prefixed by A or B as its always associated with a set of points to the entrance or exit to another line. The 'A' end is normally closest to the controlling signal box. Link to post Share on other sites More sharing options...

Coombe Barton Posted November 23, 2012 Share Posted November 23, 2012 I have to admit that correct terminology is not high on my list of priorities when the blasted things lose detection................ On the contrary you're probably using the precisely correct terminiology for how you view it at the time. Link to post Share on other sites More sharing options...
