Calgary (Alyth Yard)

Alyth Yard sits at the convergence of four CPKC subdivisions — Brooks (east to Medicine Hat), Laggan (west to Field, BC via the Spiral Tunnels), Red Deer (north), and Aldersyde (south to Lethbridge). The yard's 168 acres handle approximately 2,200 cars at full capacity, with satellite support from Ogden Park Yard and the Calgary Intermodal Facility (CIF) at Shepard to the east.

Access for railfans is limited compared to mainline spots. The primary public vantage point is the Blackfoot Trail overpass at the north end of the yard. The walkway on the north side offers a distant but elevated panorama of the yard throat, ladder tracks, diesel shops, and the convergence of the Laggan, MacLeod, and Red Deer subdivision tracks. The south side of the overpass has no walkway and is not pedestrian-friendly. Vibration from heavy road traffic on Blackfoot Trail makes tripod-based video impractical from the overpass.

Alyth Road SE parallels the east side of the yard and provides ground-level views through fencing. A CPKC yard map sign is posted alongside the road. The south end of the yard is not publicly accessible. For mainline action, the Brooks Subdivision east of the yard along Shepard Road and 114 Avenue SE offers better unobstructed photography opportunities.

The yard occupies a flat industrial area in Calgary's southeast quadrant, within the Alyth/Bonnybrook neighbourhood. The Bow River flows nearby to the west, and on clear days the Rocky Mountain front range is visible along the western horizon. The adjacent Ogden neighbourhood, established in 1912 alongside the CPR shops, retains some of its early-20th-century residential character with mature trees and older homes bordering the rail corridor.

The E. Hunter Harrison Campus — CPKC's corporate headquarters since 2013 — occupies the former Ogden Shops site immediately south of Alyth Yard. The century-old brick industrial buildings of the original shops create a distinctive backdrop alongside modern corporate facilities. Calgary's weather is highly variable: summer brings long daylight hours with dry air and high sun, while winter can see temperatures of -30°C interrupted by dramatic Chinook wind events that can warm the city by 20+ degrees in hours. Winter conditions produce dramatic exhaust plumes from idling locomotives.

As CPKC's busiest Western Canadian yard, Alyth operates around the clock handling classification, locomotive servicing, car repair, and crew changes. The yard serves as the home terminal for crews running north to Red Deer (95.6 miles on the Red Deer Subdivision) and west to Field, BC (136 miles on the Laggan Subdivision through the famous Spiral Tunnels).

Traffic is overwhelmingly freight: grain hoppers from the Prairies, unit potash and sulphur trains from Saskatchewan, crude oil tank car sets, and double-stack intermodal containers moving between Vancouver and eastern Canada or Chicago. The nearby Calgary Intermodal Facility at Shepard handles most container traffic, with Canadian Tire being a major customer. Local switching jobs include the Burnco Job, which serves Nutrien AG Solutions (covered hoppers), Burnco Rock Products at Shepard (cement), and the Shell Calgary Terminal via the Barlow Lead.

CPKC's modern GE AC-series locomotives (ES44AC, AC44CW, AC6000CW) dominate mainline power, supplemented by SD70ACU and SD60M units. Yard power includes GP38-2 and GP20C-ECO switch engines. The former hump classification yard — which once had 48 tracks using a Pro Yard II computer system — has been removed, and all classification is now done by flat switching.

Photography at Alyth Yard is more challenging than at open mainline spots due to limited public access and fencing.

Blackfoot Trail overpass (north end): The primary vantage point. The north-side walkway provides an elevated view looking south into the yard, capturing the ladder tracks, diesel servicing area, and locomotive consists. A 200-300mm telephoto lens is essential for isolating individual units from this distance. The Calgary skyline is visible to the northwest, providing a useful backdrop in late afternoon light. Note: heavy road traffic vibration makes tripod video difficult.

Alyth Road SE (east side): Ground-level views through chain-link fencing. Morning light favours this side. A telephoto lens can shoot between or through fence links to capture switching moves and parked consists. Less dramatic than the overpass but allows closer proximity to equipment.

Brooks Subdivision east of yard (Shepard Road area): For unobstructed mainline photography, the area along Shepard Road south of the double-track Brooks Sub between Barlow and Glenmore offers cleaner shots of through-trains entering or departing the Calgary Terminal. The 114 Avenue SE area near Wildrose is another option for eastbound/westbound trains.

The Alyth neighbourhood takes its name from a former CPR railway station, itself named after the town of Alyth in Perth and Kinross, Scotland. The yard grew alongside the adjacent Ogden Shops, which began construction in May 1911 with a workforce of up to 5,000 men and formally opened in March 1912. Named for I.G. Ogden, former Vice-President of the CPR, the shops were the only CPR heavy repair facility between Winnipeg and Vancouver and became the single most important economic driver for early Calgary.

During World War II, the Ogden Shops locomotive building was stripped of its machinery and converted to produce 3-inch naval guns and mounts for Bofors anti-aircraft guns, turning out $30 million worth of war materiel. Locomotive repair work was temporarily shifted to CPR's Weston Shops in Winnipeg and to the Alyth facility during this period.

At its peak, the Alyth classification yard featured 48 tracks and an automated hump system using Pro Yard II computer controls. The hump was eventually removed and classification converted to flat switching. In 1996, CP relocated its corporate headquarters from Montreal to Calgary. In 2013, the offices moved to the Ogden Shops site, renamed the E. Hunter Harrison Campus. Ogden Shops ceased locomotive and car repair operations in 2012, closing a century-long chapter. The campus now houses CPKC's corporate offices, the Canadian Rail Traffic Control (dispatch) center, and the railroad's fleet of heritage equipment, including the famous 4-6-4 Hudson No. 2816, a 1930-built H1b class locomotive that returned to steam in 2023 after an extensive overhaul.

Alyth Yard is rare among major classification yards in that key public roads — Blackfoot Trail and Alyth Road — provide legal vantage points into the facility without requiring special access. While the views are distant and obstructed compared to open mainline spots, no other location in Western Canada offers this level of visibility into a Class I railroad's busiest yard operations.

The presence of CPKC's corporate headquarters at the adjacent E. Hunter Harrison Campus adds a unique dimension: heritage equipment including Hudson No. 2816 is stored on site (though not publicly accessible), and the yard occasionally hosts special moves related to the CPKC Holiday Train program, business trains, and heritage locomotive testing. The convergence of four subdivisions means a variety of train types and routings pass through in a single session — eastbound manifests, westbound intermodal, northbound grain trains, and southbound unit trains can all appear within hours of each other.
