Pylon schemes
Contents
Overview
This page is not a catalogue of all lines and schemes, just those schemes that have a name. Not sure what this page is for but it had to be split out from the series page as part of disentangling the confusion between scheme designations and tower suite designations. The entries are only in the vaguest hint of a meaningful order, as virtually nothing is known about any of these schemes.
See the regions page for a guide to the regions and their abbreviations.
Primary Lines
Original CEB/CEGB PL schemes, plus later schemes of 132 kV and above.
The Watshams SEE PL7 tower drawings are variously annotated with the identities of other schemes, but no other scheme appears on all of them. Thus, without inspecting each one individually it’s not clear to what extent they re-used the SEE PL7 towers. Hence “Watshams?” below. (There are other Watshams tower types but only one 132 kV type is known; the others were for secondary lines.)

Secondary Lines
33 kV and 66 kV on lattice towers, mistakenly referred to as “pre-Grid” towers. Tower diagrams pending some way to name the different tower types on this site.
| Scheme | Tower type | Route | Route code | Date | Comments |
|---|---|---|---|---|---|
| MEE SL1 | Milliken E102 | “Lincolnshire area” | From 1929 | ||
| MEE SL2 | J L Eve C15/C23 | From 1929 | Seems to have been treated as one scheme | ||
| NEE SL1 | Darlington–Northallerton | HO-SA | |||
| Malton–Scarborough | HO-SC | ||||
| Malton–Whitby | HO-SD | ||||
| Harton–Sunderland | HO-SE | ||||
| Sunderland–Dunston | HO-SF | ||||
| Dunston–Hebburn | HO-SG | ||||
| Hebburn–Harton | HO-SH | ||||
| NWE SL2 | Milliken/Blaw-Knox T163 | ca. 1929 | Also SL2A | ||
| SEE SL2 | Watshams | ca. 1929 | Only recovered drawing is the D60/DT, same tower as in SEE SL3 | ||
| SEE SL3 | Watshams | ca. 1930 | D60/DT as SEE SL2 | ||
| SWE SL2 | Milliken E177 | ca. 1932 | Apparently also SWE SL3 | ||
| SEE SL4 | Watshams | ca. 1934 | Seems not to be the same suite as SL2/SL3 but not enough drawings recovered to be sure | ||
| NWE SL4 | Blaw Knox | ca. 1936 | |||
| SWE SL9 | J L Eve C333 | Bath–Melksham | Drawings appear to have been drawn in 1936 and approved in 1948 | ||
| SWE SL10 | “33 kV at Salisbury (132 kV)” | ||||
| SEE SL8 | Watshams | Rayleigh–Southend | Only the gantry drawing recovered | ||
| SWE SL11 | Blaw Knox K9906 | ca. 1947? | |||
| SWE SL4 | Blaw Knox K9906? | SL4 noted on the K9906 D30 GA diagram instead of SL11 | |||
| NWE SL9 | Watshams 132 kV? | Copies of the SEE PL7 D10 and D30 drawings were found annotated “N.W.E. - P.L.6 & S.L.9.”; these are 132 kV towers so it’s not clear what SL9 encompassed. |
