Diesel-Electric Drive in 2020

The other day as we passed through Deepwater Range on our way to a job-site in New Jersey, a scene seen multiple times a day, caught my attention. Sitting in the racks at Whitehall were the Staten Island Ferry “John F. Kennedy” and the Governors Island Ferry “Lt. Samuel S. Coursen”. To the average commuter, these are just a pair of tired old ferry’s – 55 and 64 years old to be exact. Both of these boats are somewhat dinosaurs now – especially since both are powered by Diesel-Electric Drive. Both have been going back and forth next to each other on the same route, since being built.

The JFK was built in 1965 as part of the 3 boat Kennedy class, consisting of the “John F. Kennedy”, “American Legion” and the “Gov. Herbert H. Lehman”, built at Levingston Shipbuilding. The trio were big ferrys of the time – 297′ long and could carry 3,055 passengers and 40 automobiles. Powering the boats were 4 EMD 16-567C engines which each drove a generator. In turn, 4 propulsion motors feed into a single output reduction gear set that drive the propeller – one motor/gear on each end of the boat.

Coming in at about half the size of the JFK, the “Lt. Samuel S. Coursen” has also been plying the same route since being built by John H. Mathis in 1956 for the US Army – who at the time occupied Fort Jay on Governors Island. The Coursen became part of the USCG fleet, with sister ferry “Pvt. Nicholas Minue” when the USCG took over operations on the island in 1966. The pair of boats were designed by Eads Johnson, who designed several NYC area ferrys including those owned by the Electric Ferry Company – one of which, “The Tides” would become a fleet mate to the duo running to the island in 1969. Unfortunately, I have no idea what originally powered them (The Tides was powered by a Cleveland 6-278A) – other then they were repowered in 1965 – and again later on in the case of the Coursen with a Caterpillar, however the original Diesel-Electric propulsion was kept.

NYC DOT has a new order of ferry boats on the way, one of which will be the replacement for the “John F. Kennedy”, which has been the spare boat for some years now. Even being the old boat on the roster, she is still used almost every day. DOT also has a trio of other modern ferry’s, the “Spirit of America”, “Senator John J. Marchi” and “Guy V. Molinari”, each powered by 3 EMD 16-710G3B engines driving an AC drive Diesel-Electric package. The “Lt. Samuel S. Coursen” also has a new fleet mate that arrived in 2019, the “Governors 1”, however she is only equipped to carry passengers, thus the Coursen should be around for a few more years.

Each year the number of Diesel-Electric drive boats is fewer and fewer…

Milwaukee Firsts

Nope, I am not talking about Pabst Blue Ribbon, or Miller High Life.   This past week I found myself heading to Wisconsin for a meeting and opted to make a stop over by where Great Lakes Towing operates in the Port of Milwaukee.    A pair of Great Lakes Firsts are spending this winter laid up in there. 

Back in the Menominee River, sits the tug North Dakota.   North Dakota, built in 1910 by the Towing Company, was the first “G Tug” converted to Diesel propulsion.   North Dakota was converted to diesel in 1949 by Paasche Marine Service in Erie, Pennsylvania, to plans laid out by Tams Inc., and Great Lakes Towing Company.  Under the hood so to speak, is a Cleveland Diesel 1200HP 12-278A, that was shipped 2/23/1949, part of order number 5641.  These engines drove Falk 12MB reverse reduction gears that swing a 102″ wheel.  Order 5641 encompassed the propulsion for four tugs, including North Dakota, Arkansas, Vermont and Illinois.  Today, all four of these tugs are still in service.

North Dakota had some major engine work done recently, and hopefully will be in the fleet for a few more years.   The crews in Milwaukee keep their boats looking sharp.   North Dakota would be a great museum piece one day, a true testament to the “G Tug”, now going on over 100 years old, and having spent more time with Diesel engines now, then their original steam plants.

Back at the Kinnickinnic River in the Port, is the Stewart J. Cort.   The Cort was the first 1000’ ship built for the Great Lakes, abit in an odd fashion.  The bow and stern sections were built by Ingalls Shipbuilding in Mississippi, welded together and sailed to the lakes.   On arrival, they were split apart, and a mid-section was added by Erie Marine, also in Erie, PA. The Cort went into service in 1972, on a run she still handles today between Superior, WI and Burns Harbor, IN.   The Stewart J. Cort is powered by a quartet of EMD 20-645E7 engines, rated at 3600HP each.  Each pair of engines drives an Escher Wyss controllable pitch prop.   EMD supplied several of what were essentially locomotive parts for the Cort, including many traction motors that power the Bow and Stern thrusters and various pieces of unloading equipment.

In front of the Stewart J. Cort, is the tug Louisiana.  While not a first, she was converted to diesel as part of the 2nd order of engines in late 1949 for Great Lakes Towing.  Unlike the first batch, all these engines were WWII surplus that went through Cleveland Diesel’s rebuild program and emerged as brand new engines with new serial numbers.   Louisiana’s engine originally powered the Landing Ship – Tank # 935.  For all intents and purposes, she is identical to the North Dakota. 

I am going to throw this one in also for the hell of it. On my way back to the highway, Amtrak’s Empire Builder was leaving. While I can’t say railfanning interests me like it used to, I opted to get a quick shot. In the lead is Amtrak 182, a 19 year old General Electric P42DC, followed by two more. Amtrak has begun the process to replace these tired engines with new Siemens Chargers…which, to put bluntly, are ugly as sin. But hey, they said that about the EMD F7 once upon a time also..
