Do the instructions need updating then, because quite a few folk on here if just using RTT etc. will
only have the scrambled code and won't have access to the 'real' one? Likewise, on one of the data sources I use (and I believe other folk use) you can also search using the scrambled one and it's often a good way of finding the service (indeed sometimes it'll appear under the scrambled one, but not the real one).
I think as long as people know they're not the "real" headcodes and that the real one is preferable
if they have it - as it may help the loco IDs be found more readily. Otherwise, I believe the more info that can be provided the better in terms of helping others locate the service/ID (i.e. a scrambled headcode is better than no headcode at all).
As an example I was able to find the loco/unit IDs for the working
@Cundy66 saw using both 742S
and 7X20 - with the "742S" quoted in the post it was a 5 second job; without it would've taken longer and required some detective work to find the train that was being referred to.
Maybe one for
@bb21 to look at as moderator/author of the original instructions...?
