They shld give 1398G return to revenue svc. Kns bus didnt had a
chance to do revenue service and it was already a perm
TRG since birth.
1398G replaced 439B as training back then, Notice how the '94
Hispanos didn't receive any extensions back then, and not much time
for the 95-96 Hispanos back then?
But when most of the O405s were de-registered back in 2014, They
used most of the volgrens (959S-962G,966X-968R,970H-972C) for TRG
and 958U 963D-965Z got converted last this year. Notice the reason
why they picked the volgrens over the MANs, and 191S got picked to
replace 830D back then?
So more or less it should be done on a FIFO basis and if the B1
goes, they can use the B3s to buy some time just like they did with
the volgrens.
