Commuters in Vienna, Austria have turned their noses up at scented subway trains after a month-long trial aimed at enhancing their travel experience.

Four aromas - including "energizing" grapefruit and "relaxing" melon - were tested in the Austrian capital during July.

The city's public transport company said Monday it dropped plans to "scent"the trains after 21,000 of 37,000 participants voted against the plan in an online survey.

"I want to make sure that passengers feel comfortable in public transport," Vienna environment councilor Ulli Sima said.

During the test run, the scents were funneled through ventilation systems.

Vienna's public transport used by 2.6 million people daily is known for its efficiency and low cost.

Almost half of Vienna's 1.9 million inhabitants hold a 365-euros ($407) yearly pass.

The number of pass holders exceeds the number of registered cars in Vienna, according to the transport authority.
