I have no hard evidence but I remember reading that the final 160km/h working ended a just a couple of years ago.
In the mid 90's Deutsche Bahn, too, ran containerised parcel trains at 160km/h for DHL/Deutsche Post, under the name "Parcel Intercity". The parcel trains still run, but nsurpringly, in the modern world of sectorisation where all the extra infrastructure/energy costs of higher speeds are billed back to the operator, and all 160km/h locomotives are ordinarily dedicated to passenger work and have to be cross-hired to work goods traffic, the finances didn't stack any more.
