Yes — it ships with a factory-installed ESU sound decoder with the full 8-notch GEVO prime mover, 4 selectable air horns, and 2 bells.

It negotiates 18" radius curves, though 22" or larger is recommended for best appearance and performance.

What era is this locomotive right for?
The ES44AC was introduced in 2003 and is still in front-line service, so it fits any modern-era Union Pacific layout.
