The wording of the West Coast Railways announcement gives little hope and little confidence-
This suspension of this service is due to a debate with the rail regulator around door locking. We share the regulator’s commitment to safety and our priority now is to work with it to renew permission to enable us to run The Jacobite on the main rail line.
That is species wording. There is no debate, nor does it suggest that they are actually doing any work to make the required modifications or to find alternative rolling stock. Most of the rest of the Heritage Rail Industry has complied, WCR have had all winter to make the required modifications, having lost the "debate" last summer.
One option that has apparently been floated is to run the Jacobite slower, thus messing with the timings of the ordinary service trains. No thanks. And as if slower makes safer.
That closure of the "debate" last year followed several previous warnings, which WCR thought they could just ignore.
It doesn't matter what the public think, they do not make the rules. So far the only action by West Coast Railways has been along the lines of saying the area will lose x£million from us not running.
That is not and cannot be a consideration regarding safety.
The thing is, that WCR have been involved in several other serious incidents away from the Jacobite.
As was written above it is totally strange why WCR have made this a matter of principle. They run a number of other passenger services with the required rolling stock, so know and have made the required mods to other of their train cars.
