Rolling stock query for Brussels to Luxembourg in early 1970s

[StephenHunter]

What sort of rolling stock would you have found running between Luxembourg City and Brussels around 1972? I know the line was 3kV electrified and used SNCB locos.

It's for an RPG I'm running.

A few international trains hauled by belgian HLE 23 or 26, and made of any possible mix of belgian, French, Swiss, and Italian international rolling stock.
One fast Brussels Luxemburg train pair (the Grand Ducal) made of some 4 or 5 belgian K coaches hauled by an HLE 23.
Mostly clockwise semi fast service made with the at-that-time-ubiquitous green two cars EMUs, with split en route at Jemelle to form the omnibus to Arlon. Sometimes a "budd" inox emu instead of a green one.
And a few rush hour trains with HLE 23 or 26 hauling a rake of 8-10 M2 cars.

Thanks. That will be useful.
