Overhaul and Maintenance of Rail Deisel Engines and Gensets and Related Services

Iarnrod Eireann-Irish Rail

Iarnród Éireann (IÉ) has an operational fleet of DMU and Intercity push pull train-sets equipped with diesel main traction engines and generating sets (together referred to as ‘the engines’).
IÉ has a requirement to undertake planned overhaul work and casualty repair on these engines.
A high quality fixed price all inclusive overhaul and repair is required that builds on current reliability levels and improves where possible. Technical innovation and product enhancement is encouraged and high level warranty support between overhaul events is essential.
Engines will be overhauled to an agreed programme. Installation and removal on the vehicle is excluded.
The engine and Gen-sets types are as follows;
Traction engine
Class 2600, 2800: Cummins NTA 855-R1, 4 stroke turbo-charged, capacity 14 litres, 350 BHP. An engine mounted compressor is fitted to all types.
Class 29000: MAN D2876 LUH, 4 stroke turbo-charged and intercooled, capacity 12 litres, 294kW (400 BHP), Euro 2 Emissions
DMU generator engine
Cummins 6B5.9GR, 4 stroke naturally aspirated and developing approx. 75 BHP. Small variations exist around peripheral equipment e.g. water pumps.
DMU generator alternators
The alternators fitted to the Cummins 6B5.9GR generator engines are as follows:
Class 2600 Alternator: Nishinon 3-phase generator
Class 2800 Alternator: Nishinon 3-phase alternator
Class 29000 Alternator: Letag 3-phase alternator
All Alternators have common outputs of 230v AC single phase & 400V AC 3 phase at 50 Hz. There is also a 24vDC electrical supply on the vehicles for battery charging and to supply emergency equipment e.g. lighting.
On board diesel power generation for Locomotive Push-Pull Coaching Stock

The vehicle is equipped with two diesel generator sets. The engine used is a turbo-charged 430BHP four-stroke V8, engine model NO. 2848 LE202 and is manufactured by MAN. This is mechanically coupled to a 330kW 3 phase AC alternator manufactured by LETAG. The Gen-set operates at 1500rpm.
