After the grand welcome of the first-ever cable car service in London last week, another unique initiative with 2012 Olympic tourism in mind is in the works. 

The bin men and sweepers in the city of London can be your next guide experts. According to reports, the workers will be trained to provide directions to overseas visitors, as well as keeping the capital's streets clean.

Tourists can now call these unusual sources of advice to ask for directions.

Around four million tourists are expected to visit the capital this summer, with an increased volumne during the Olympics. 

"Our street sweepers and bin men are some of the friendliest faces in town," Cllr Ed Argar, cabinet member for city management and transport said to reporters. "So much so, that as well as keeping the city clean, they often become the unofficial tour guides for London."

More than 1,000 sweepers and waste collectors will be trained to improve their customer service skills, and equipped with pocket-sized maps to help point tourists to make the upcoming Olympics event more trouble free.

"This is a great example of how England is pulling together to ensure all our visitors during this amazing year are given an outstanding welcome," VisitEngland's head of business development Jeremy Brinkworth said. "We are sure that London's road sweepers will help to form a great first impression for visitors from throughout the UK and overseas."

Veolia Environmental Services will be offered in four London boroughs: Camden, Lambeth, Tower Hamlets and Westminster, all of which are expected to receive a high number of visitors this summer.

"This initiative will increase that engagement and make the millions of people expected this summer feel even more welcome," Argar said.
