Yes they can be isolated as indeed they used to have to be when a 221 and 220 worked together. But you still have to know about the systems even if isolated. And we no longer have the competency
Ah that makes sense, I suppose you never know when the isolation might fail! Many thanks!
I'm getting more of a "you have to be able to isolate it in the first place and without tilt training this isn't a standard task for drivers" vibe rather than an "isolation might fail" one, but I'm ready to be corrected.
Thats true. I was thinking of a situation where a driver who signs tilt bring a 221 to a location where it is coupled to a 220. They then isolate the tilt and leave. The non tilt signing driver then takes both units forward.
