Central Line Timetable
Peter Corser wrote:
The half minute timing accuracy was down to the programme (sequence) machines stepping every half minute. The timetables on the machines ran in half-minute time (from 0300 to 0300 the next day) with 0 at midday - half minute time was the most you could do within the limits of a computer integer (8 bit - +/-32767 IIRC). A good job they didn't have computers back in the 1920s then - the Central London Railway used to run its off-peak trains at intervals of one and seven-eighths of a minute. (Or 32 trains an hour.) -- Joyce Whitchurch, Stalybridge, UK ================================= |
