This is an interesting question, but in most cases, apart from the body shell, would most of the locomotive be like Triggers Brush?
triggers brush, the ship of epheseus, the train of dangie - all the same really
Pendolinos have still got a way to go to match the highest HST power car mileages, as per my previous post, and 91131 is reported to have achieved around 8 million miles before being laid up at the end of 2021 (https://www.railmagazine.com/news/n...s-record-breaking-91-saved-for-bo-ness-museum), while others were reported to have covered "over seven million miles" at around the same time, so the remaining active class 91s probably still fall a little way short as well - though not by much, despite their shorter lifespan, particularly against the HST power cars that still remain in UK passenger service.
Although this was true, the Deltics were notable competitors for miles per year, as the HSTs (and Pendolinos, 91s, etc) typically stood in depot sidings overnight, whereas the Deltics, somewhat slower, nevertheless ran pretty much 24x7, being on overnight trains returning to their starting point, often with just a few hours turnround at both ends for a considerable period. Of course, they didn't last nearly as long. Possibly connected.
They each covered around 3 million miles over their 20 or so years in BR service. 9010 was the first BR diesel-electric to achieve 2 million miles in service, in January 1973.
What's the Train of Dangie?
The highest mileage was for 43238 and 43239, as per the piece in Rail - note that the info was from 125 Group, so is more accurate than if Rail had worked it out.
The NMT diagrams are not as intensive as the TOC diagrams were. East Coast had the highest mileage diagrams.
My first thought was 003. I reckon pendolinos are a good shout, as well as some 158 that's been going around on long-haul regional services since it was built.
158s on Lime Street - Norwich ?
The leading Pendolino's must be nearing 7.5-8 Million Miles (roughly 1k per day, 330k per year, 23 Years...The highest mileage was for 43238 and 43239, as per the piece in Rail - note that the info was from 125 Group, so is more accurate than if Rail had worked it out.
Both power cars would likely have got to 10 million miles before they were taken out of service. 43239 is likely now the highest given its stint on XC before export.
I doubt it, considering the amount of time they have probably spent in yards or hauling slow freight.
Too much time spent ‘on the ground’ at Derby I would say.
Again, doubt it, as it is not the fastest route. Mileage will be greatest for the fastest trains I would imagine?
Extrapolating from the figures I shared earlier, the highest performing class member might be at around 6 million miles now.
As I noted above, the remaining operational 373s are probably around 3 million miles shy of the highest mileage HST power car.
Yeah, I left 43238 out of the equation, as it's been in store in recent times compared to 239.The highest mileage was for 43238 and 43239, as per the piece in Rail - note that the info was from 125 Group, so is more accurate than if Rail had worked it out.

Quite impressive for the 373s considering they are about 20ish years younger than the 43s
Much of the Scotrail fleet is ex-GWR power cars, which, typically, weren't diagrammed quite as intensively as their East Coast brethren, so it might take a little while to even up the difference. Plus, are individual Scotrail power cars being worked that hard over the course of a year or more? I get the impression, from threads on here, that some are doing more work than others.
Quite right, it's a good part of the reason why higher speed trains end up withdrawn around 20+ years after introduction - they cover that much higher mileage in that time.
In terms of the ex-VTEC power cars that have found themselves onto test train duties (not necessarily NMT, I lose track now admittedly), it has to have to added to an already high total, even though they're not necessarily diagrammed daily.
No ScotRail HST is doing 1000 miles per day. Plenty of the GWR diagrams didn't used to do anything like 1000 miles and they had 125mph running.
