Mallet Engines on the Saltville Branch - When?

[nw-mailing-list at nwhs.org]

When were Mallet engines first used on the Saltville Branch?  Were the Z's 
used there before the Y's?  (It's probably an issue of when the bridges timber 
bridges, which were still there in the 1960s !!!, were strengthened.)

Perhaps Bennos Blevinoshevski or some of the other Bristol Line Wizzards have 
given thought to this matter...
