I think more and more Batch 1 Euro IVs are being used for
TRG.
22/101 of the units are currently being used for TRG. That's
more than 1/5 of the Batch 1 EEIV KUB fleet.
Think I posted on the previous page or something, the reasons
are quite obvious: their ride quality are just not as "refined" and
"smooth" compared to the later batch KUBs. The vibrations from
idling, the road noise and gearbox grinding sound are very much
evident on the first few KUBs compared to the later ones.
Quite obvious then why SBST pulls the earlier ones out from
revenue svc to do TRG.
