Overview

Key Features
Precision ABS shell with cast-metal chassis for exceptional durability and prototypical heft
Die-cast metal pilots, trucks, fuel tank, detailed side grilles, and moveable roof fans
Horizontal CAN-motor drive with sprung axles for smooth, quiet operation
RP25 metal wheels on metal axles, plus Kadee-compatible coupler mounts on 2-Rail models
Full lighting suite: Rule 17 headlights, illuminated number boards, LED ditch lights, LED running lights, interior cab lighting, and backlit gauges.
Detail enhancements: brass handrails & horn, hand-painted cab, and unmatched exterior detail
Advanced electronics: 3R ERR Cruise/TMCC/Railsounds compatible with TMCC/Legacy/DCS, 3R Conventional for your choice of sound, and 2R ESU Loksound 5.0. Blunami is available as well
Operational flexibility: Runs on O-54 curves (3-Rail) and 48" radius (2-Rail)
Robust performance: precision flywheel motor delivers powerful head-end pull and prototypical slow-speed control
 
Heritage Paint Schemes
Each paint scheme is meticulously researched and faithfully reproduced, complete with accurate decals, dynamic numbering, and era-specific details:
UP Heritage Fleet: Showcases six distinct “fallen flag” schemes honoring Missouri Pacific (No. 1982), Western Pacific (1983), Katy (1988), Rio Grande (1989), CNW (1995), and Southern Pacific (1996).
Norfolk Southern Heritage Fleet: A rich black heritage design celebrating the historic Norfolk & Western or Southern Railway lineage
Ferromex: Sharp Mexican road colors with crisp logos and numbering
CSX, KCS, BNSF, and MRL: Correct contemporary liveries with vibrant paint gloss and fine detail
 
Why It Stands Out
 
This SD70ACE isn’t just a beautiful model, it captures the complete prototype experience in O Scale in a quality that will rival late run brass...
 
In summary, the Sunset Models 3rd Rail SD70ACE unites superior engineering, detailed finishes, and operational realism in a versatile platform. Whether you’re honoring North American rail history with heritage schemes or showcasing modern liveries like UP, NS, MRL, CSX, BNSF, or Ferromex, this locomotive is a striking and performance‑rich centerpiece for any layout.
 
NOTE: Heritage units will require at least 10 reserved to be produced. Tell your friends if you want to see a specific one come to life...
