The background image in this X-ray analysis sotfware page shows what looks like a trolley or train car on tracks with a sign that says "X-ray Now: Everybody over 14 years old".

Where might this have been and when? Was this practice widespread worldwide at some time in the past? What was the advertised purpose, and if there was an underlying purpose different than that, what might it have been?

    The first MRIs too I think. Modern versions now travel the countryside in trucks. These pieces of equipment were too expensive, and in need, to sit inside a building with low access from the population. – Mazura Jan 15 at 4:47

    An X-ray machine in a car parked near our school building annually, and we were made to go and have our chest images taken, in order to detect diseases, I guess. Maybe it's still done so in Russian schools. – CopperKettle Jan 15 at 12:14
  • @CopperKettle I think xray imaging of schoolchildren no longer needed as they are vaccinated against tuberculosis these days – Džuris Jan 15 at 18:10

    @Mazura It's actually not need, MRI/CT machines are actually "mobile" because of Clinton-era healthcare rules which discouraged hospitals from investing in infrastructure when other hospitals in the area had the same capabilities. Sticking it on a truck trailer made it no longer a capital improvement to get around those rules. The one at our local hospital hasn't moved since it was put in, there's gardening all around it. – user71659 Jan 15 at 19:53

    I don't think this is worth it's own direct reply, but related to public mobile x-ray machines was the old "Shoe Fitting Fluoroscope", which was basically an x-ray tube that you put your feet inside of and then stared down the barrel of... en.wikipedia.org/wiki/Shoe-fitting_fluoroscope – Aaron Lavers Jan 16 at 6:10

It was in Glasgow in 1957, as part of the city's fight against tuberculosis. It's worth noting that the X-Ray machines weren't actually on the tram. It was simply used to advertise the campaign.

Illuminated tramcar

Mobile X-Ray units were used in the UK (the Mass Miniature Radiography (MMR) programme), but in vans, rather than trams. Similar mobile units were actually brought back into use in London in 2005 to tackle a rise in TB cases in some areas of the city.


This page from the People's History of the NHS explains about the 1957 advertising campaign in Glasgow in a little more detail:

Despite reduced incidence of tuberculosis in England and Wales, Scotland, and in particular Glasgow, had been dogged by tuberculosis throughout the immediate postwar period. By the 1950s the Department of Health for Scotland was committed to reducing the incidence of the disease by creating an X-Ray campaign accompanied by a media 'blitz'. As part of Glasgow's X-Ray campaign against tuberculosis, 11 March to 12 April 1957, Glasgow Corporation produced this large advertisement to be displayed on the side of a tram car in the city.

    I see, this is more recent than I expected. Thanks for the lightning-fast answer! – uhoh Jan 15 at 2:49

    @uhoh My father's side of the family come from Glasgow. I had seen pictures of that tram before. I also remember 'No spitting' signs on Glasgow buses when I was a boy in the 1960s! – sempaiscuba Jan 15 at 2:52
  • Any plans to address the 'world-wide' angle? (Currently, this is very focused on the OP pic and 'surroundings') – LangLangC Jan 15 at 15:07
  • @LangLangC I'm not sure what you mean by the 'world-wide' angle. The campaign was limited to the City of Glasgow. Or are you referring to the practice of mass X-Ray screening to detect and treat TB (sadly still not a world-wide phenomenon - which is why the mobile screening units were brought back into use in London in 2005!). – sempaiscuba Jan 15 at 15:45

    @LangLangC Ah, OK. Given that X-Ray machines weren't actually installed in the tram, I read that as "was it a widespread practice to advertise in this way", rather than "was screening for TB widely practised". Fair enough. – sempaiscuba Jan 15 at 15:57

Though it was not on public transportation, busses were used in Denmark in the 1950's as mobile platforms for tuberculosis detection.

Since 2014 similar mobile X-ray equipment has been used to detect tuberculosis among homeless.

This was certainly very widespread, with variations, in many places or nations around the world. The purpose was to mass-scan the populace with healthy or harmless X-rays for signs of tuberculosis and other illnesses in the picture of the lung.

One of these mobile devices is on this informational pamphlet:

enter image description here
Pamphlet detailing the Mass Miniature Radiographic Unit, manufactured by Siemens, dating from the mid-Twentieth Century. The pamphlet shows the floor plan and a variety of internal pictures of the Unit to show the suitable arrangement of the Unit. Presumably produced as part of the advertising output of Siemens for this unit, the pamphlet provides the viewer today with a visual map of how the Unit might have looked during their major deployment from the 1940s until the 1960s.

In the US it was just like that:

General Electric reported that the army had just purchased 45 of its 4 x 5-inch photoroentgenography units for shipment to various induction centers throughout the country. The boned looking private on the right was proudly identified as an inducted General Electric employee.

In Germany there was a Röntgenreihenuntersuchungen 1939-1983 and some of these were mobile:

enter image description here
Inside one such mobile unit, West Germany –– Gütersloh: Röntgenreihenuntersuchung im Röntgenzug Sauerland, 1957 Foto: Gütersloh, Stadtarchiv | BB19837 Internet-Portal "Westfälische Geschichte" | https://www.westfaelische-geschichte.de/med2473

The procedure as such – the Röntgenreihenuntersuchung – although not mobile, was continued in the German army until 1999.

Even now such mobile units are in use:

Zweites Leben für Röntgenbus

Ein Röntgenbus wird in Thüringen für die Untersuchung von Flüchtlingen auf Tuberkulose eingesetzt. So können Krankenhäuser entlastet werden. Eine Arztpraxis wertet die Aufnahmen binnen 24 Stunden aus.
enter image description here
Das Röntgenmobil steht in Erfurt vor der Thüringer Staatskanzlei. Der Bus wird bei der Erstuntersuchung von Flüchtlingen auf Tuberkulose eingesetzt.

The reach of that procedure was at 85–90% of all inhabitants in 1982 when they detected 4,6 infected people per 10.000.


Q What was the advertised purpose, and if there was an underlying purpose different than that, what might it have been?

As always with Germany, it has to be brought up that until 1945 there were around 150 doctors involved in this screening in a less than desirable "underlying" aim for it.
Radiological sterilisation and castration. (src) 2% of all 360000 undergoing this procedure were 'treated' with x-rays.
