- only farce with pacer local doors is that only a single leaf opens!
Yes, I've experienced
SDO▸ on a 143:
I caught the 1519 from Melksham to Chippenham, for my connection to Bristol Temple Meads. I was the only passenger waiting at Melksham: the 1519 was a 143, with two staff in the front cab. The train stopped, and I pressed the door open button opposite me (at the rear of the train): no reaction, but the conductor gestured me right up to the front of the train (single door opened only) for me to get on the train! I dutifully jogged up to her single opened door, squeezed in, and we departed.
