A rail trail is the conversion of a disused railway track into a multi-use path, typically for walking, cycling and sometimes horse riding and snowmobiling. The characteristics of abandoned railways—flat, long, frequently running through historical areas—are appealing for various developments. The term sometimes also covers trails running alongside working railways; these are called "rails with trails". Some shared trails are segregated, with the segregation achieved with or without separation. Many rail trails are long-distance trails.
A rail trail may still include rails, such as light rail or streetcar. By virtue of their characteristic shape (long and flat), some shorter rail trails are known as greenways and linear parks.
The only carrier to exist in Bermuda folded in 1948 and was converted to a rail trail in 1984. Some of the former right of way has been converted for automobile traffic, but 18 miles are reserved for pedestrian use and bicycles on paved portions. The rail bed spans the length of the island, and connected Hamilton to St. George's and several villages, though several bridges are derelict, causing the trail to be fragmented.
The Kettle Valley Rail Trail in British Columbia uses a rail corridor that was originally built for the now-abandoned Kettle Valley Railway. The trail was developed during the 1990s after the Canadian Pacific Railway abandoned train service.
The longest rail trail in Canada is the Newfoundland T'Railway that covers a distance of 883 km (549 mi)). Protected as a linear park under the provincial park system, the T'Railway consists of the railbed of the historic Newfoundland Railway as transferred from its most recent owner, Canadian National Railway, to the provincial government after rail service was abandoned on the island of Newfoundland in 1988. The rail corridor stretches from Channel-Port aux Basques in the west to St. John's in the east with branches to Stephenville, Lewisporte, Bonavista, Placentia and Carbonear.
