Years ago (probably 1995/96) I bought the Hornby Eurostar 4 unit pack (engine + dummy + 2 carriages and track). I think this was R1071? May be 1-3 years later I purchased a 2-carriage expansion pack (may be R4013C?). However, the carriages in the expansion pack were significantly taller than the original 4 unit pack and it looked silly. I am sure the real Eurostar 373 doesn't have such a height difference between carriages? I sold all of it a few years later.
I see they released a newer 4 unit pack and a 6 unit pack, along with first class carriage pack since I sold all my stuff.
Which item had the incorrect height/is there a product to avoid purchasing?
Do the more recent models (class 373, not 374) have a newer mould, or it's the same level of detail?
