Together at long last. Three ZJ1s owned by two Australian customers and one American customer, Westralia Transportation, Sacramento Southeastern and Victoria National, sit next to each other at Sunset Gulch's Wolfram Yard to have their group photo taken. Another SSE unit can be seen on the left.
The Zhòngxíng yùnshū Jiāoliúdiàn 1 (literally: heavy haul, Alternating Current, Type 1) is a 4,250hp diesel-electric locomotive built by the China Railway Rolling Stock Corporation (CRRC) and their predecessor, the China South Locomotive & Rolling Stock Corporation (CSR) from 2011 to the current day.
Frustrated with the lack of interest in their products from western countries, starting in August 2010, CSR jumped straight into the deep end and developed a mainline heavy haul freight locomotive for the ultra competitive North American market, citing class leading fuel efficiency and compliance with the US EPA's Tier 4 emissions standards in a package being sold at a rock bottom price as key marketing points. At the same time, German diesel engine manufacturer MTU Friedrichshafen were looking to expand their portfolio by offering a 20 cylinder version of their 4000 series engine to any diesel locomotive builder wishing to utilise their product in a heavy haul application.
The first locomotive was unveiled at the CSR Ziyang factory in 2011. Final assembly for units destined to American customers initially took place at CSR's Hegewisch (Chicago) facility, in compliance with the Buy America Act of 1982. Those destined for customers outside of the United States are built in China at either CSR's Ziyang or Qishuyan plants. On the 1st June, 2015, CSR and rival China Northern Locomotive & Rolling Stock Industry Corporation (CNR) merged to form CRRC, allowing for increased production capacity of these locomotives. Since the merger, final assembly for US market units now takes place at CRRC's Springfield facility as well as Hegewisch, while production for everywhere else started at the former CNR Dalian plant, working in liaison with Qishuyan and Ziyang.
In 2021, thanks to customer feedback, CRRC heavily refined the design to create the Gen 2 variant of the ZJ1. Over 200 changes were made, including a new exhaust muffler, revised grille arrangement and updated electronics.
The main difference between the Gen 1 and Gen 2; the exhaust.

Notes
(1) AC electrical gear is three-phase. Value shown here is for a single phase; the value used by RLC PT2 should be 3 times the value shown. This is done by typing "*3" (without quotes) after the number value when editing the locomotive config in the E2 editor.
(2) Australian SDA1s have two compressors, presumably to speed up air recharging times compared to just one compressor. Value should be double what's shown here in PT2.
