West Kirby ? New Brighton ? I think are barred to 23 m stock ? Then the Loop needs tripcocks. So that is essentially the Wirral no 158s ? And doubt they've ever done Liverpool / Southport or Ormskirk ?
In addition to where they have been, although already covered in other posts, 158s (159s) have done Waterloo - Southampton - Bomo - Wareham - Swanage charter / railtours for HRT at least 4 times (and I was on 2 of them).
Have they ever worked on MML south of Syston anywhere to StPancras / any cross London junction ? In 36 years since moved to Luton I can't say I can recall one. But I don't necessarily pay attention to it all.
