Light weight bogies vs passenger comfort.

[Roast Veg]

The problem is inherently low specification train interiors being not fit for purpose, often combined with primitive foreign suspension arrangements which are unsuitable for our infrastructure.

mods note - split from here

It's less about the suspension being "foreign" and more to do with the ultra light bogies used on new stock. It massively reduces the maintenance burden on both the TOC and NR, at a cost to passenger comfort.

Some of these imported designs of ultra light bogies produce unacceptable levels of passenger comfort when used on our infrastructure, so they are effectively incompatible, hence “foreign” as opposed to the native bogie designs of BR stock which see very few complaints over passenger comfort. It’s just unfortunate that these unacceptable bogies are often combined with equally unacceptable seats on new stock.

Actually in at least one rather notable case, the lightweight bogie is a UK design now exported all around the world. In the linked article, it describes bogies in the UK being lighter than their continental counterparts even in the 90s. Older, heavier BR designs are simply no longer acceptable.

God knows why, I’d list them as one of the worst riding lightweight bogies out there. The Siemens design being the best.

Cost, unsurprisingly.
