LIRR #152 Builder Plate

The LIRR MP15-AC Engine Roster


By the early 1970's , the LIRR was looking to replace the first L1's (C420's), RS1's, Rs3's, and S1's. ALCO was not building engines in the US and the carrier was not buying MLW engines from Canada . The serious option considered was GE and the UB18's . However, when the new Master Mechanic came from the Milwaukee Road (which just ordered MP 15's), the order was placed for MP15's and the GP38's.

The class "E15's" were mostly used on the Oyster Bay branch. Rarely were they used as power to KO ( Ronkonkoma ), but were used on the weekday scoot to Greenport (GY). There were times they were used as a second unit to Pt. Jeff and Montauk on heavier trains, but this was not the norm as the heavier Montauk trains rated two E20's (GP38's)

In the later years, the LIRR used them as HEP units (600 VDC HEP, another LIRR oddity). OB trains would have one at one end running HEP, the other pulling the train, or a GP-38-2 at the other end. The HEP unit would idle at notch 3 or so I think, and not supply traction power. This lasted until the bi-levels came on. Bizzare but it worked and IIRC, the LIRR saved good amount of $ doing it...

The Chief Mechanical Officer at the time selected them. He felt, as most Long Island railroaders at the time believed, that a small road switcher would be the best choice for our operation. The short-haul-quick-turnaround type of scheduling was ideal for a road switcher. The unit would accelerate quickly and had a top speed that could keep our schedules.

They were also very low cost and inexpensive to operate, which was quite important at the time they were purchased. The Milwaukee Road had lots favorable experience with EMD products and the CMO had been a former Milwaukee Road employee.

History would show that they were a good selection for the job and an excellent replacement for the RS-3's.

As was stated above, the LIRR had a long history with ALCO products, but they were unfortunately no longer available. Had they been, then the LI would have most likely remained an ALCO customer.  LI Tool

The yard is the one on West John St, west of the Hicksville station and across from Nassau County's Cantiague Park. NYAR has it now & it's where the Twin Forks ex-PRR LIRR steel hack is. Behind the loco is the mainline, west is to the right. The track I'm standing on and the one to the right lead into the yard behind me. The loco is on a siding that runs east. Info: Al Castelli

Notes on the MP15s with "P" numbers:
Some MP15ac's were converted to a power cab option and numbered with a "P" before or after the road number. This option allowed the throttle to be set to an equivalent of notch 6 to turn the generator at a steady speed. Energy was channeled to a 4-point jumper to the train. These conversions allowed these engines to supplement the Alco &  EMD cab unit power cabs which had problems in cold weather. These operated in push-pull service with another MP15ac or a GP38-2 as the motive power.
Dates of the conversions:
#171 was first unit, converted to full power cab configuration on 1/19/82, then to the option in 2/82
#170 in 1/82
#169, #172 in 2/82
These four units were surplus power from freight service.
The following are in number order:
#161 in 4/84
#162 in 2/84
#163 in 11/83
#164 in 10/83
#165 in 10/83
#166 in 10/83
#167 in 9/83
#168 in 8/83 
#167 had "hump" (creeper) control, but it was removed when given the power cab option and put into #150.
#168 had Microphor L.T.P. (Low Temperature Protection) unit installed in 3/83.
