Last summer I was a traveling technician in a 1966 luxury railway car.
Since the electrical stuff was constantly giving us hassles I dug into the original documentation.
I found the car once had a special Lenco turntable designed to play HiFi in a moving railway car... it also had an Uher Report reel-to-reel and a HiFi radio. The amplifier was a boasting 8W!
Every compartment was fitted with a Blaupunkt car radio.
Unfortunately the salon equipment is long gone and the car radios don't work any more.
