Some perspective, the scare stories in the press are maliciously misleading, omitting to mention WCR poor safety record and the fact that other operators have complied with a request to fit CDL and continue to run steam specials. We are talking about one operator running trains on the mainline, and this has little relevance to heritage lines running at slower speeds. To suggest that all coaches used on these lines be CDL fitted is just scared mongering. Aside from the cost being prohibitive one of the joys of visiting lines like the SVR, Bluebell and IoW is to travel on historic coaches. These are working museums offering the chance to recreate travel in days gone by, and to make too many sacrifices in the name of H&S would diminish that experience.
Mainline running is different, and stricter rules need to be applied. Fitting CDL on the Jacobite trains is unlikely to detract from the experience, where the main attractions are steam haulage, scenery and recreating a Harry Potter journey.
