The buses have been provided by Warner Bros. Studios Leavesden and bus operator Golden Tours to transport key workers between West Herts Hospitals NHS Trust's three sites, reported Variety.
"Our workforce has been depleted due to sickness or self-isolation and so it's really important that those staff who are well but have transport issues can come back," Variety quoted Paul da Gama, chief people officer at West Herts Hospitals as saying.
"A special shuttle bus, which will have strict social distancing rules, is the perfect solution and we are so grateful to Warner Bros. Studios Leavesden and Golden Tours for making this happen. Our staff might not be travelling to exotic locations or seeing behind the scenes of a major movie, but they will be making magic happen in their own way," he added.
The free service runs its first journey just after 6 a.m. and its last drop-off at 10:40 p.m. (local time) between the Trust's three sites.
"We couldn't think of a better way to use the buses at this time. We are delighted to play a part in supporting our local NHS in its time of need," Variety quoted a spokesperson for Warner Bros. Studios Leavesden as saying.
The UK has reported more than 90,000 confirmed cases of coronavirus while the toll due to the coronavirus has surged past 12,000.
