Introduction
The SD60ACC locomotive is a modernized version of EMD’s classic SD60 series, designed to improve efficiency, sustainability and power. Rail operators face increasing pressure to meet stringent emission standards while managing high freight demands. The SD60ACC answers these needs by combining improved AC traction motors, emission compliance and improved fuel economy in one versatile machine.
What is the SD60ACC?
The SD60ACC is a rebuild of the older SD60 locomotive, replacing the DC traction system with an AC motor. These improvements give the locomotive improved efficiency and ensures compliance with the latest environmental standards while providing increased reliability when transporting heavy loads over long distances.
Technical Specifications
horsePower: 3800 HP (with EMD 16-710G3B engine)
Ton Motor: Improved AC motor for improved performance and reliability.
Fuel apacity: 4900 gallons
Top speed: 70 miles per hour (113 km/h)
Weight: 415,000 pounds (188,000 kg)
Autonomous operation: Designed for long-distance intermodal and freight transport
These specifications ensure that the SD60ACC can efficiently handle demanding rail operations while minimizing downtime. Also read Geekzilla CES 2023
Environmental compliance and sustainability
The SD60ACC meets EPA Tier 1+ standards, resulting in significantly reduced emissions compared to previous models. With the optional Tier 2 upgrade kit, this locomotive ensures reduced nitrogen oxide (NOx) emissions and particulate matter, making it an attractive choice for environmentally conscious operators.
Fuel efficiency:
Thanks to an improved traction motor and emission control system, the SD60ACC offers 10-15% improved fuel economy compared to its predecessor.
Carbon dioxide
reduction:
A single SD60 ACC locomotive can reduce CO2 emissions by several tonnes per year compared to previous models, helping rail companies meet their sustainability targets.
Real World Applications
The SD60ACC plays a vital role in several railroad networks.
Norfolk Southern – Used extensively for intermodal and heavy haulage in the Midwest.
CSX Corporation: Deployed for intermodal freight on long-haul routes.
Canadian National (CN): Tested the viability of cross-border service between the US and Canada.
These examples demonstrate that the SD60ACC excels in both freight and long-haul operations.
Historical Evolution of the SD60ACC
The SD60ACC has a rich heritage and evolved from the previous EMD SD60 model.
SD60: Introduced in the 1980s with an emphasis on power and reliability, but with limited emissions control.
SD60M – Features a spacious cabin for increased crew comfort during long voyages.
SD60I: Added sound insulation for an improved operator experience.
SD60ACC – Incorporates modern AC motors, digital controls, and improved emissions compliance to turn an older model into an efficient, sustainable machine.
