Why does the entreprise fail so much. I took two trips recently and both times the service had failed however I do think its not happening as much now.

In simple English the engine overloads as it has to run the train and provide HEP to the train. It puts the loco's under a great deal of stress which is why they fail a lot. To avoid this the loco are changed around often and any loco that operates the entreprise will operate on the Mark 4 on Cork line which HEP is not supplied from loco and on Freight servces from Dublin to Waterford and Ballina to give them a break.

Currently Mark 3 generator are being/had a refurb and will operate on the entreprise soon which will greathly help the loco's. There was a test run recently and all went well.

NI owned loco 8208 had such a bad failure rate it was operating on freight services for months before it went back to the entreprise

Why do the locos keep failing? Surely providing HEP for significant amounts of time was in the specification when they were ordered?

I thought they were similar in many ways to Class 67s which have no such problems?

You would have thought. Post two answers both your questions though.

A mismatch of locomotive and rolling stock, hampered by a generation in which there has been almost complete shift from loco-hauled services to DMU operations thoroughout Ireland (north and south). Plus the de Deitrich stock used on the Enterprise are odd balls... Not much commonality with other fleets and certainly not enough to ever run hourly services.

Because the engines cannae take any more!

That's surprisingly accurate.

When the 201s wete ordered GM strongly advised the railways to include an auxiliary engine on the loco for Head End Power (ETH) but were ignored

But why would this be neccesary?

Couldn't they just not use the top notch on the power selector while providing ETS? Or just derate the traction system to reduce the stress on the power plant.
400kW being used for ETS applies the same stress as 400 additional traction kilowatts.

This just seems like someone screwed up the calculations.

I'm not familiar with railways outside of the UK and Republic of Ireland, but surely 2h00-2h15 to cover 113~ miles makes it one of the slowest end-to-end inter-city services in Western Europe?

IR-Mark4/ICR · 22nd June 2012, 18:04

It is very slow but there are two main factors. Very speed restricted around Dublin Area and 90mph is max limit in NI which dosn't help.

If this really is the case isn't there calls for new trains all together or are the faulty trains relatively new?

You appear to have missed post #2 of this thread? Also the Rolling stock section of the Enterprise Wikipedia page may help.

Removed.

The obvious answer would've been not only to use the Mk3 Genny Vans, but also the Mk3's themselves to boost the rolling stock fleet. The genny vans look well in Enterprise livery.

In regards line speed, it does tend to slow remarkably down when approaching Dublin. As far as I can tell this is due to IE prioritising local services over the intercity.

fastest time Belfast > Dublin in 1991 book 1 hour 55 for 111 class (nearly 1,000 HP less than a 201) plus up to 10 mk IIs on a Friday on 70/75 mph Max GNR vintage bull head rail on wooden sleepers and semaphore signalling. Hmmmmm.
