The Wells and Walsingham Light Railway says Anglian Water repaired a water main on Stiffkey Road in Wells but left a digger and temporary traffic lights in place after the work was completed.
The narrow-gauge heritage line connects Wells and Walsingham and runs for about four miles through the countryside.
Although the digger has since been removed, the traffic management remains, causing long tailbacks and preventing drivers from turning into or out of the railway.

Nick Champion, the railway’s managing director, has blasted the traffic lights as “unnecessary” and “unprofessional”.
He says the disruption has already cost the business several thousand pounds as it was forced to close while the water main was initially repaired.
Though Anglian Water’s system says that further work is still required at the site, Mr Champion believes this simply relates to removing the traffic lights.
He said: “Everyone’s facing a hard time at the moment.
“What we really didn’t need was something that unnecessarily causes delays and congestion.

“People who want to turn into our entrance can’t because there’s queuing traffic.
“It’s so frustrating when everyone’s trying to earn a crust. It’s the last big weekend of the season, a bank holiday weekend, and Anglian Water, who supposedly love every drop, don’t seem to care.
“They are effectively causing traffic disruption on a Bank Holiday weekend with traffic lights doing nothing at all.
” You couldn’t make this level of ineptitude and poor planning and coordination up.
“It would be funny if it wasn’t such an inconvenience to our business and affecting the visitors and residents of Wells.”
Anglian Water have been contacted for comment.
