I'm not sure anyone has mentioned the maximum permitted speed on this curve - it is 25 km per hour, equating to 16 mph. I believe at the time of the accident it would still have been pretty dark given the time of year, also the weather conditions. The BTP have stated the tram was moving 'considerably in excess' of this speed. I believe the theoretical top speed of these trams is 50 mph, not that they should get anywhere near approaching that speed at any point ever. I also know from having been in Croydon by sheer chance when the first-ever public tram went through that there was almost a tragic accident by the almshouses at the end of George Street when a toddler ran out in front of it - only the tram bell, which was an afterthought to the original plan, being deployed saved him being struck.
