When was the last time the entire Metropolitan Line was closed for the weekend for engineering works?

[jimbo]

Presume that is for reversal of test trains outside the new signalling area. Maybe will also apply to future testing of the remaining SMA areas?

Probably only a SMA9 issue - for SMAs 13 and 14 I would envisage a reduced service but not a complete suspension.

Any idea yet of the number of closures for SMA9 testing are planned (assuming all goes perfectly) ?
I see the next SMA8 test weekend is in Oct , but at least one other planned for the changeover in 2025?

No more planned closures for SMA9 testing before commissioning early-2025.
