Wainfleet - interesting equipment

Unread postby John Hinson » Mon Apr 2, 2018 8:22 am

Some interesting equipment at Wainfleet, on the GNR's Skegness line:

It is the tall wooden device on the windowsill that interests me here. This is cropped from a larger image but even on the original the detail isn't good although I can just make out the top and bottom labels read "Down xxxxx" and "Up xxxxx" but I couldn't even guess what the middle one reads. The xxxxx looks longer than the words "Line" or "Main".

The block switch here is interesting - does anybody know the function of the two plungers at the top? Again this picture is cropped from a larger one, but I can't make out the brass plates above the plungers. I think I may have seen this type elsewhere. I don't know if there is any significance but this box is one of many on the line provided with a clsong switch despite controlling a level crossing.

I'd be interested to learn what purpose the above items serve.

On further thought - is that actually a closing switch? Because there seems to be one of those further down the shelf!:

The two pin sockets look like those for maintenance circuit telephones. We had loads of those on location cases on the southern end of the WCML. I still have my plug fitted handset somewhere in the garage.... :wink:

Regarding the big box with knobs on, nearby Little Steeping had two:

(apologies for the quality of the picture- you (JH) were there when it was taken, so maybe you have a better one! :D )

As far as I recall, last time we had this discussion we concluded they were something to do with trolleys.

Yes, I was wavering on the trolley idea - that must be where the idea came from. But it seems a luxury for a lightly used double-line with reasonably short sections.

Sadly nearly all my pictures from that day with you (1988) have deteriorated beyond the abilities of the best editing software, but thanks to your reminder I discovered that fortunately Norman did the business:

And close examination of the original reveals the answer. The left-hand label reads "Trolley Release" and the right hand "Switch Release".

Thanks for the pointer.

These trolley release instruments are rather fantastic. I have had one working with a Tyers No6. I still have all the bits to make it work. The handle moves itself to the mid position on receipt of a release with a very satisfying clunk.

Here's a GE one wire with Trolley..

The plug points in the box were used when testing the trolley token and phone.

They almost look like a wooden version of a Scottish Region Tokenless instrument!

The internals of a trolley instrument..

There is a ball bearing at the base of the herringbone switch locking the contact column. When the lock is operated the ball bearing is forced out of it's aperture by the spring loaded contact column causing the handle to jump to mid position.

What i've not seen in any photo's is how the trolley telephone attracted the attention of the signalman. I have some hooters that came from the Wensleydale line that would have worked with the LNER(NE) type of gear. They work just as well with LNER(SA) circuits so the telephone arrangements must have been similar. I can post a picture of my pair of hooters if anyone is interested.
