IET bodyshells: surface coating failures, or corrosion?

[whole diary]

[Mark A]

There's a Twitter thread running on the subject of visible corrosion involving LNER^» (London North Eastern Railway - about)'s IEPs^▸ (Intercity Express Program / Project. This will offer more capacity on routes, save money, give a consistent and safe service and meet customer requirements. Intended to replace HSTs.), which put me in mind of a photo from December (hopefully visible below) showing either a failure in the surface coating or corrosion around a GWR^▸ (Great Western Railway) IEP window. It's reasonable to wonder if these trains are going to have 'A problem'.

Regarding the LNER twitter thread, someone's remarked that water ingress at the windows is causing issues as it's able to travel to where it can cause galvanic corrosion. LNER's trains run in a somewhat salt-rich environment, and GWR's even more so, and this cannot help either.

Ah, but don't forget, both Hitachi and GWR have assured us that their IETs^▸ (Intercity Express Train - replacement for HSTs (manufactured by Hitachi in Kobe, Japan)) are 'Dawlish proof'

But only if not allowed to run in the worst conditions, an IET confined to the depot should survive Dawlish just fine.

Suggest merging this thread with the main "problems with IETs^▸ (Intercity Express Train - replacement for HSTs (manufactured by Hitachi in Kobe, Japan))" thread.
