More of a 'refresh' than a 'refurbishment' on the ATW 153s I think. Certainly not as much of a makeover as the ATW 158s. Legroom and tables are both still in rather short suply on the refreshed 153s, but I think ATW did raise the seats to give short people a view.
The refurb is still in progress - there are some looking very smart and shiny and others which are extremely tatty!
Internally? I think the ATW 153s were refreshed by the time the ATW 158 refurb programme was complete. However, the refresh did not include an external re-paint, which some units seem to have received more recently (ATW's class 150s are getting the 'ATW-WAG livery' also).
I was at Cardiff today and noticed the 142s have the same upholstery design as the 158s... Is this rolling out across the 150 142 and 143 fleet? Quite smart
Interesting, I wasn't aware of any work to the Pacer fleet. Did the 142 in question have fresh paintwork too?
