Western Railroad Discussion > The UP SD59MX 9900 with the blisterDate: 12/23/18 09:55 The UP SD59MX 9900 with the blister Author: Barstool The date is 2012- august 28th and the Redding turn is departing Roseville with the 9900 in the consist with the blister for testing....9900 is now normal looking and the blister is gone, but it sure gave the 9900 some personality.

I haven't heard much, but I assume the one's out now are reliable good power?

Date: 12/27/18 22:27 Re: The UP SD59MX 9900 with the blister Author: alamode That size prime mover went into all of the SD59MX rebuilds and has nothing to do with the "hump".
The official summary of the project: "The base platform for this project was an EMD SD60M locomotive that was repowered with an EMD 710ECOTM engine, which is U.S. EPA-Certified and manufactured by Electro Motive Diesel (EMD). This project utilizes a prototype Tier 2 12-710 engine to provide 25 percent increase in carbody space for application of the EGR system along with a larger cooling system. Diesel particulate emissions were to be reduced by installing aftertreatment equipment. The aftertreatment device consists of diesel oxidation catalysts (DOC) and diesel particulate filters (DPF) in series, integrated with the experimental EMD 710ECOTM, twelve-cylinder, 3200 bhp, two-cycle engine. The experimental engine had been designed for the EGR system and included a new turbocharger with sufficient boost to accommodate the DOC/DPF. EMD is committed to commercialize this advanced aftertreatment technology after the demonstration phase proves the aftertreatment to deliver acceptable performance, durability, serviceability and reliability." For those curious about the blister: "The tray is 219” X 125” x 42” and weighs 9000 pounds." The result? "The goal of this project was to provide an experimental locomotive that achieved greater than an 80 percent PM reduction from Tier 2 levels. Actual PM emissions were 95 percent lower than Tier 2 levels and well below the Tier 4 line haul standard of 0.03 g/hp-hr. Also of note, hydrocarbon (HC) emissions were reduced by 90 percent."

(EMD) and Union Pacific Railroad (UP) from August 2012 Date: 12/28/18 01:04 Re: The UP SD59MX 9900 with the blister Author: exhaustED Great info., thanks.
