How interesting you say that.

This caught my eye for a couple of reasons. Firstly it was interesting for me to see a forum member with knowledge of the old HST trainsets.
Secondly because it bought back happy memories when I was personally involved with a number of design and type-testing activities related to the both HST power cars and the original Mk3 coaching stock.
Those original HST Power Cars (maybe you already know) were equipped with Paxman Valenta engines.
I just wondered London_Manila, if like me, you might be Railway enthusiast?
I was lucky enough to get a number of visits to Australia on the back on my involvement with HST (Class43) simply to work on their XPT. The original XPT power cars also used Paxman's.
Apologies to the OP for my off topic.
Maybe time for Trains thread
