About 29,000 trips were registered on the system on day one. Government data from the first five days shows the number grew to about 64,000.

It is important to note during that time there were only two business days and it was also school holidays.

Transport Canberra was thrilled with the number of people using the light rail and expected the number to grow significantly from Monday.

"Transport Canberra didn't have any firm expectations for patronage in the first week, given we've never operated light rail before and given it covered a lot of public holidays," a spokesman said.

"We've been delighted, though, with the use of the service so far."

The spokesman added that each new school term saw an increase in the number of people using public transport.

Transport Canberra officers will placed throughout the network to help with people acclimatising to the new network.

Of course, the first week did not go entirely smoothly, with one tram breaking down on Tuesday because of a software issue.

The tram was able to continue after having its software rebooted, however there were reports of it stopping and starting repeatedly and causing delays along the line. One passenger said the air conditioning had also failed and some passengers became uncomfortable while they were stuck in the stationary tram.

The spokesman thanked passengers for their patience while teething issues were resolved with the new networks.

"We of course always try to minimise the number of teething issues we might have," he said.

"When they do occur, though, it gives us a chance to understand what the issue was and take steps to reduce the risk of it happening again."

The return of school on Monday coincides with the launch of the new bus network designed to integrate with the light rail system. It also kicks off a month of free travel on both the buses and light rail.

The new bus network has garnered criticism since it was announced, particularly from parents as a number of dedicated school bus services have been scrapped.

The concern is that school students, some very young, now have to catch multiple buses to and from school when they previously only had to catch one. They also have to attend bus interchanges unsupervised.

It has also been suggested the new network disadvantages the elderly and people with a disability.

The spokesman said Transport Canberra hoped the month of free travel would allow many Canberrans to learn about the new network and how it affected them, and encouraged new users to adopt public transport.

"The light rail network and the bus network have been designed to be an integrated public transport network to make it as easy as possible for as many Canberrans as possible to move around our city," he said.
