A seasonal odour in railway cars linked to wall insulation foam
In a case study of Australian passenger trains, volatile chemical compounds released by water from insulation foam in the car walls were identified as the likely cause of a seasonal, objectionable odour reported by travellers and drivers in the railway cars; the authors considered it unlikely that bacterial colonies in the air-handling (HVAC) systems were the odour source.
One case study of odour-affected trains in Australia, in which insulation foam taken from the car walls was exposed to simulated temperature and humidity combinations in a climate simulator to recreate the odour. It concerns one unwanted odour, not the everyday smell of train carriages; the cause is stated as likely, not proven, and the abstract does not name the compounds.
The statement the claim rests on was found word for word in the abstract fetched from the named service, and an editor read the full abstract against every part of the claim. Abstract from Europe PMC (ebi.ac.uk/europepmc).
