Nothing yet. As seen in earlier posts, they’ve been given a deadline to sort it out.
Until then, the LNER staff are being told to be extra vigilant.
I have an inkling that the reason this might not apply as much to GWR is that all the Series 1 OLE is newer, and follows the standard European clearances between platform & OLE of
3.5m (alongside reduced live envelopes with the Single Insulator "gooseneck" Cantilevers), while the ECML Mk3a/Mk3b OLEMI-vintage equipment is nominally follows the British Standard clearance of
2.75m, alongside more live OLE components.
As such, I feel that the case of the "death ladder" is more pressing on the ECML than the GWML, although I think that the GWR 800s/802s should receive similar modifications for the sakes of safety and uniformity when a permanent solution is found.
