You've been telling us what annoys you about commuting in London. It follows a report which shows children have fuelled a rise in bad behaviour on buses, tubes and trains.
It's been revealed that an eight-year-old boy was found trespassing on London Underground tracks at the weekend.
The child was spotted on the tracks near Stanmore last Saturday and was led to safety by a cleaning contractor.
The news comes after a 12-year-old girl was hit by a tube train in Brixton yesterday.
Bob Crow, leader of the Rail Maritime and Transport union, said the two incidents raised "serious questions" about plans by London Mayor Boris Johnson for driverless Tube trains.
