Might there be a geographical factor for where other EMUs caused 92s to shut down? ISTR the Preston area was notorious for it; coincidentally, Preston (and indeed Crewe & Carlisle) were descoped from the WCML Autotransformer Upgrade programme, which included installation of Return Screening Conductors (RSCs) in the signalling troughs. RSCs absorb electrical interference as they deliberately have a larger cross section than the other cables in those troughs.Whilst they do have 92s they are only used for Cally sleeper work and some tunnel freight. Getting them cleared on the MML will more be an issue of their electrical interaction with the 360s and 700s as modern EMUs have a habit of causing a 92 to shut down.
This hopefully shouldn't be a problem on the MML as it all looks scoped for AT as things stand.
