Talk:3105: Interoperability

Well, it is not interoperability that would be the potential problem, but potential interconnectedness. Some systems are just not meant to be connected to the rest of the network`21:48, 20 June 2025 (UTC)

There will be more interoperability concerns than the track gauge. Such as the up stop wheels. And side wheels. Henke37 (talk) 21:55, 20 June 2025 (UTC)

> "two standards: US rail systems predominantly have a 143.5cm gauge" Why cite "US"? 4 ft 8+1⁄2 in was developed in England. The US got confused and Abe Lincoln is credited with ordering first 5' (won't work) then 4 ft 8+1⁄2 in (most US rails were so close to 4'8.5" that they mostly changed in a weekend). Rest of world used UK or US machines, or copied them, with the main exceptions fading away over a century. (Well, Australia was still jacking cars mid-route when I was young.) https://en.wikipedia.org/wiki/Track_gauge#%22Standard%22_gauge_appears The width of two horses' asses, a Roman chariot, is often cited as if pre-industrial mechanics standardized. --PRR (talk) 05:39, 21 June 2025 (UTC)
