GEML is arguably in a terrible state. The infrastructure falls to bits on a regular basis and there are numerous speed restrictions popping up all over the place. There has been a huge emphasis put on a complete new fleet for the line in recent weeks/months/years. The intercity sets are likely to be replaced in 2020 or maybe slightly before and it remains to be seen what will happen with the rest of the stock. The big issue is though even if you order a complete new fleet for the line you are still not going to achieve Norwich in 90 nor perfect punctuality with the current state of the line. Network Rail have a massive backlog of work to do, with numerous level crossings and foot crossing that really need closing need closing but huge amounts of opposition to that. So how on earth do solve the issues on this line?
