Trog Posted January 16, 2019 Share Posted January 16, 2019 The surveying and setting out was still being done the same way in the 1980's, although by more casually dressed technical staff. 2 Link to post Share on other sites More sharing options...

Trog Posted January 16, 2019 Share Posted January 16, 2019 (edited) What's the idea of the bushes or ferrules in some of the chairs? All chairs and baseplates held down by chair screws have ferrules, did you notice the use of the dolly cup to ensure the ferrule was not overdriven into the chair, they should be about a 1/4" proud? This gives a bit of give in the joint between chair and chair screw, and also acts as a filler between them. Otherwise without any give the screw could break the relatively brittle cast iron baseplate/chair, and as soon as there was any slacking of the screw it would loose its grip on the chair. The chair would then shuffle under passing trains and start digging a hole into its sleeper. Edited January 16, 2019 by Trog Link to post Share on other sites More sharing options...

RMweb Gold beast66606 Posted January 17, 2019 RMweb Gold Share Posted January 17, 2019 A couple of screen grabs to show where the work site is located. Hoole Way road overbridge, beyond the bridge Chester No.4 signal box is the dark shape to the left, Chester GW loco shed is to the right - some locos are vaguely visible, on the near right is the end of the current platform 4. Chester No.3A (LNWR) is the overhead structure to the left of this shot, the current platform 7 is visible through the legs of the box. Vehicles are visible on the right in whats now platform 2, in those days there were more bay platforms. The footbridge which was once at the West end is also visible, with a wooden signal gantry in front of the footbridge. 1 Link to post Share on other sites More sharing options...
