"Trains due to pass through Roma Street station were held at other stations including Central, South Brisbane and Milton while the alarm was investigated." Mr Nicholson said about 18 services were affected.
"These train services were stopped within a five-kilometre radius of Central station," Mr Nicholson said. "Luckily we were able to slip out the front there and get some fresh air." Ms Nugent said commuters remained calm, despite fears there may have been a bomb on a train.
ANTANANARIVO, Madagascar - Some 55 dolphins have died after coming ashore on a beach in the north-west of Madagascar, conservationists said today.
And rescue crews were working to save a pod of dolphins that became stranded in a river in south-west England. In Madagascar, the melon-headed whales, a species of dolphin, were first spotted at sea last month, but then became stranded on a beach last week, Herilala Randriamahazo, from the Wildlife Conservation Society, said.
"We haven't seen a stranding anywhere near this scale since 1981, when pilot whales were beached on the east coast. Woodley said the striped dolphins normally did not swim near coasts, but perhaps they had moved in to feed on fish attracted to a large algae bloom.
Firefighters were called to help rescue a squirrel which had been stuck up a telegraph pole for two days.
The animal-loving crew arrived at 10.15am and pitched their ladder up to the pole.
About 18 train services were affected by this morning's faulty alarm at Roma Street railway station, which forced the evacuation at 8.40am of hundreds of people at Brisbane's second busiest train station.
Train services were stopped in a 5km ring around Brisbane Central Station during the emergency.
"The community safety work we have done over the years has paid dividends and we have seen a huge reduction in fires and other incidents.
"Alongside that, advances in technology, excellent firefighter training and modernised ways of working are allowing us to work smarter." The plan also includes moves to improve fire cover in the evenings and weekends by increasing the hours day-crewed firefighters respond immediately from their station by an extra 35 hours a week.
