Last Saturday (29.10.2022), the Swiss, on the occasion of the 175th anniversary of railways in the country, broke the more than 30-year-long record for the length of a passenger train previously owned by the Belgian railways (wiki). The train consisted of 25 four-car EMU Stadler Capricorn trains. Its total length was 1906 meters. If this event were to be transferred to the OTTD world, this train would be 50 tiles long... It means that there is still a possibility of breaking this record.
