After a highly splendid recent trip to the Isle of Wight, utilizing the Island Line frequently I have became quite knowledgeable about the Class 484s. On my trip during between the 22nd and 25th February 2024. Meanwhile apart from them being extremely charming and well designed (At least for the passenger that is) I spoke to three different guards who were rather happy to have a detailed chat, Though they all had one straightforward answer, which was (These units are a nightmare) or (Let’s not get in to this conversation). The consensus is clear that reliability is woeful. During my visit the only units operating were 484003 and 484004. While the latter three were out of service due to failures of some variety. I am interested to understand if anyone may relay any information to what variety of failures the units are experiencing, seeing as the main bane of the 230s was the engines and insufficient cooling systems, which is not present on the 484s. on a more positive note I found the units to be quick of the mark and internal arrangements to be ideal. Unfortunately though ( As with the 230s) the doors are painfully slow to open and slam violently when closing. It can not do the bodyshells any good!
