With all the budget cuts and the wrangling that goes on, I'm half expecting to wake up one morning and hear that the DfT is exploring options on extending the lifetime of pacers and extending them with middle carriages to help with overcrowding :P I have only ever travelled on a pacer once and that was all the way from Manchester Oxford Road to Salford Cresent and I hit my head four times as we went over points (I was standing up, it was rush hour) in under 10 mins, the 185 on the way back in the evening was like a limo pulling up in comparison to the robin reliant we had on the way there in the morning
