High speed rail representatives spoke to hundreds of residents and business bosses in Sheffield to discuss concerns about the £43 billion project.
HS2 Limited booked the English Institute of Sport, in Attercliffe, to give people whose homes and livelihoods lie close to the route the chance to raise any issues.
Several dozen businesses and around 20 to 30 homes may have to be demolished. Others will be affected by noise and disruption.
Officials were on hand at the event, which ran all day on Friday and Saturday, to answer questions. There was also the opportunity to hear what trains on the new 220mph line will sound like by entering a ‘sound booth’ which had been set up.
Among those attending was Simon Blantern, director of Hi-Point Access, which provides equipment such as cherry pickers and is based off Grange Lane, Ecclesfield.
His company has benefited from a slight change to the route in north Sheffield, to take the line away from major firms near Meadowhall, such as the Firth Rixson steelworks.
Mr Blantern said: “When I first saw the route I thought it would go straight through our premises, but the alignment of the line has now been moved closer to the M1.
“Our company was able to come down and find out information - as a result, I don’t think we have too much to worry about.”
Other organisations visiting the exhibition to find out extra information included Sheffield Chamber of Commerce and Industry.
Ian Jordan, project director for the northern phases of HS2, said: “We had quite a lot of feedback from businesses, and people who live close by were able to discuss their concerns.
“The mood was pretty positive.”
He added: “We anticipate between 20 and 30 homes may have to be demolished in South Yorkshire. The route is set to be approved next year.”
HS2 is set to open in 2032/33 with a station at Meadowhall.
