In the UK, traveling sorting offices which went up and down Britain were phased out in favour of mechanical and automated post sorting. However, Royal Mail still has a few BR Class 325 EMUs which carry parcels and priority mail up and down Britain overnight by rail.
In France, La Poste has the use of a TGV operated by SNCF which carries parcels and priority mail between major cities. Named the "TGV Postal" or TGVP, these things allow for overnight deliveries in France.
In Russia, Пoчтa Poccии operates a number of trains which carry parcels and mail across many parts of Russia, though mostly Siberia. Post is a lot slower in Russia, but rail is often chosen before planes, mostly as the operating costs are a lot lower.
While these are examples of trains, with the fact that Amazon and other such online shopping services are becoming more dominant, many cities with existing tram infrastructure could use trams to carry parcels and other mail from airports or train stations to parts in the city centre without needing trucks or other vehicles. Amazon are investing in buying aircraft for global mail, but if they invested in using trams instead in some cities, they could really make their deliveries more environmentally friendly.
