CIE 001 Class

The Córas Iompair Éireann 001 Class locomotive was manufactured by Metropolitan-Vickers at their Dukinfield Works in Manchester. The 001 Class locomotive was the backbone of mainline passenger and freight train services on the Irish railway network for forty years from 1955 until the mid-1990s when they were replaced by the new 201 Class.

Engines

Crossley

Initially they were fitted with eight-cylinder two-stroke, port-controlled Crossley engines. These were a loop scavenge type, which utilised a patented principle that recycled the normally wasted exhaust-pressure pulse to boost charge air in the cylinder. They produced 890 kW (1,200 hp) at 625 rpm and could do 120 km/h (75 mph). The original sandboxes, which were utilised to improve traction with the rail, were removed after a few years.

Their Crossley engines proved to be notoriously unreliable from the start. Amongst a plethora of problems were:

• Unbalanced engines resulting in vibration-induced fuel pipe and water pipe fractures
• Cylinder defects
• Excessive water temperature causing shutdowns

There were also problems with generator and motor flash-overs.

EMD

These problems were tackled between 1968 and 1971 through the progressive re-engining of the entire class with a 1,650 horsepower (1,230 kW) 12-cylinder EMD 645E engine (a similar process was implemented for the original 201 Class). However, this power output stressed the ability of the original cooling and transmission systems and the engine output was reduced to 1,325 horsepower (988 kW) for improved reliability. When built, these locomotives were originally numbered A1 to A60, and as locomotives were re-engined, they had the suffix 'R' added to their number. From 1972, the prefix letters were dropped and the locomotives were renumbered 001 to 060.

Accidents and Incidents

• On 5 December 1963, locomotive A17 was hauling a passenger train from Westland Row to Westport when it broke down at Mullingar, County Westmeath. Locomotive A42 was sent to its assistance, but collided with the stationary train at a speed of 30 to 40 miles per hour (48 to 64 km/h). Both locomotives were damaged, sixteen people were injured.^[1]

Preservation

015 restored at Moyasta Junction, March ‘09

A39r at Downpatrick

The first locomotive to be withdrawn was 008, following bomb damage in 1973. The last withdrawal was in 1995; four locomotives of this class have since been preserved as follows:

• 003: Owned by the Irish Traction Group, stored at the West Clare Railway, Moyasta Junction.^[2]
• 015: In a gutted condition at the West Clare Railway, Moyasta Junction.^[3][4]
• 039: Owned by the Irish Traction Group,^[5] on loan to the Downpatrick & Co Down Railway where it is in full working order. It currently carries the Black and Tan livery, with high bands.
• 055: On display at Hell's Kitchen public house, Castlerea, County Roscommon.^[6]

Model

The A Class has been made as a 00 gauge kit by Silver Fox Models.^[7]
