You're right about the S/N circuit at Wood Green 4 on which reports were received from Hatfield 1 Dave C. : But it's official labelling was the other way round, AU-HT, as all circuit namings seemed to be xxx (southern end) to xxx (northern end), despite in this case it being mainly populated by boxes on, or having to report, Up trains
The 'Down side' equivalent was "YF-HT" -
- (I have a kind of manual spreadsheet of the telegr. circuits between KX and (approximately) Hitchin, showing what they were and which boxes etc. were connected to each one) -
- HT = Hitchin Telegraph Office -
- YF = Wood Green No.3 Box -
- though by the time I got to see the remaining Wood Green boxes in about '67 -'69, No.3 had been abolished a few years earlier, and 'YF-HT' actually then started back at WG No.1 (WO) : Once I'd learned S/N for train reporting
(it was used for little else by then, unlike earlier times), I recall that, as WG1 was required to do, I several times 'wired on' Down Class 4s and 6s for the signalman
(Class 5 had been re-allocated for ECS by then) from WO, to PO, JV, CT, YE, WG and SG. -
- WO = Wood Green No.1 Box -
- PO = Potters Bar Box -
- JV = Hatfield No.3 Box -
- CT = (of course,
) Welwyn Garden City Box -
- YE = Welwyn North Box -
- WG = Woolmer Green Box -
- SG = Stevenage North Box. -
- The same was also required at WG1 for late or out of course running involving Down Class 1s and 3s, as I distinctly remember one evening where circumstances necessitated sending on "one S seven 0, No" (for 1S70, not yet passed as it was late or not yet left Kings Cross), "and three S one five" (3S15) with the minutes past the hour of its passing time (3S15 was booked to follow 1S70) : -
- Very satisfying (to have learned the S/N sufficiently to do that, unaided).
