>>1625207This is a a question for the transportation board, anyways, my two cents:
1. Everyone is a cager. Even though trams can work well alongside cars, as they do in Prague, they are unlikely to get approved because even the urban planners are cagers who don't want anything to stand in the way of their huge SUV as they run over five kids at once.
The most well-developed tram networks are in places where ownership of a car by the average joe was uncommon, such as Prague or Dresden.
Not enough people travel by public transport to justify the investment.
2. They have been somewhat supplanted by subways, and in cities such as tokyo city trains, with tracks separate from road traffic.
>>1625243Don't give russia failing to maintain/develop a public works project as an example why said project doesn't work. The only time anything gets done in russia is when it's built for an oligarch.
