This then defines whether you are able to bring in heavy plant to replace rails/sleepers alongside on the other track; or whether you have to bring the rails in on trolleys and assemble manually. Most systems that have 24h services tend to have the former solution, I think London is the only system with two parallel tunnels where 24h has been attempted. New York also has four tracks on most lines which are used by express and slow (local) services during the day, whereas at night they just use two tracks at a time and work on the other two. Copenhagen is also easier to operate 24h as it is driverless.<br /><br />In terms of other cities: Warsaw and Munich run till 3am on weekends (Fri and Sat nights), Hamburg runs all night Sat nights, Rome runs till 2am on Sat nights, Barcelona runs till 2am Fridays and all night Saturdays and some holidays, Anonymousnoreply@blogger.com
