Kentville Turntable

From DARwiki
The Kentville Turntable and roundhouse with steam and diesel locomotives, 1959.

The Dominion Atlantic Railway's Kentville terminal employed a turntable to turn locomotives from the Windsor & Annapolis's establishment in 1868 until the Kentville railway facilities were abandoned in 1993. The Windsor and Annapolis built the first turntable and engine house at Kentville in 1868 south of the mainline. It consisted of a three stall engine house[1] and a covered turntable with an attached machine shop.[2] It burned in a fire on July 8, 1915.[3] The old WAR turntable was salvaged by a railway employee who installed it in his garage to turn his car[4] at his house on 476 Main Street Kentville. (The house, garage and old turntable were sold in 1957 a demolished by Irving Oil to build gas station.)[5]

A replacement roundhouse and turntable was built in the fall of 1916 by the DAR's Bridge and Building department led by foreman H. Dalton, north of the mainline. The roundhouse[6] included a 70-foot turntable serving the six stalls[7] as well as several outside storage tracks. The turntable was a 70-foot, half Deck Plate Girder turntable, a standard CPR design intended for secondary mainlines and branch lines. The Kentville turntable was one of sixty of these 70-foot turntables built across the CPR system. The bridge structures were mostly supplied by the Dominion Bridge Company and the Canadian Bridge Company.[8]

By 1920, the turntable included a Pilling Air Motor.[9] The turn table was rotated by a compressed air motor located under the control platform. The motor could be powered by compressed air from the nearby Machine Shop from overhead airlines or it could be connected to the locomotive air hose by a normal glad hand connector. The engine was moved so that the there was some weight on the air motor's wheels, and then the air cock was cracked. The air motor chuffed loudly, slipping and sliding, but eventually doing its job.

The turntable was in constant use in the steam era turning locomotives and accessing the roundhouse stalls. The 70-foot length was ideal for the DAR's 4-4-0 and 4-6-0 locomotives, although it required careful positioning for the longer 4-6-2 Pacific and RDC Dayliners, which only 18 inches to spare from the end wheels. The turntable continued in use, albeit less frequently, into the diesel era, often turning VIA Rail's dayliners, a delicate operation requiring assistance from a SW1200 to position the dayliner and power the turning motor through air hoses.[10]

When the Kentville shops and yard was closed by the CPR in 1993, the turntable was sold to a private landowner in the New Ross area who used it as a bridge to cross a small river. The air motor was ripped apart and buried in the turntable pit when the former yard and shop areas were landfilled.[11]
