Their crowning achievement was probably the 'new seat covers!' poster that appeared on a lot of 321s when they replaced the allegedly bedbug-infested FGE covers. Well done guys, you carried out some routine maintenance, have a pat on the back...
The unit in question did eventually cool down a degree or so but was still quite warm by the time I alighted. Despite the A/C issue that 1Y26 service is an absolute joy to use. No shuffling up for people to get on at Stratford and the fastest journey times I've ever had from Liverpool St to Shenfield, today coming in at 18m48, which for me is probably a record, and allowed me to reach Shenfield, cross over and then head back to Brentwood, alight and exit the station before the Eastbound TfL service I otherwise would have used had even reached Chadwell Heath. The 360s, apart from when the A/C isn't working, are pleasant and quiet to travel on and when you're used to doing most of your travelling on TfL services, are a welcome bit of tranquility.
I imagine the passengers on the preceding Norwich service on their pair of bins may have looked across enviously... They were both Renatus units but even so, quite the downgrade.
