Staff at the National Motorcycle Museum, Bickenhill were outraged after bosses were told the bus operator planned to cut the 27-year-old centre from its 900 bus route by February 28.
Director Nick Hartland warned the “ridiculous” move might force around 40 of his loyal staff to leave the attraction.
But this week, the bus company announced that following the uproar, and as part of their public consultation, the route from Birmingham Airport would not only be saved but extended down to Park Hill, Coventry.
Mr Hartland said: “There are a lot of very relieved people here. Obviously it’s a real boost for us because quite a lot of staff would have been badly affected and may even have had to find other work.
“It would have been devastating in these difficult economic times.
“We also have a number of visitors that come by public transport that would have lost out.
“It’s a complete return to common sense.”
A National Express spokesman said: “Taking the Motorcycle Museum off the route was a consideration as part of the consultation.
“No final decision had been made but obviously it was something of a concern.
“We want to make sure we get people from where they want to go and it’s good news that we have been able to achieve what everyone wanted.
“There are a lot of relieved people, that’s great.”
National Express hope the extended route will benefit both themselves and the museum by increasing passenger numbers, making it a more viable service.
“Far from disadvantaging the museum, it will actually now allow more members of staff to get work and more visitors,” the spokesman added.
