Protosounds 2.0 Upgrade for
Atlas O Diesel Locomotives

TAStudios offer the ability to upgrade Atlas O diesel locomotives with Protosounds 2.0. Now you can add the full boat of features to most any Atlas O Diesel locomotive!

Each Protosounds 2.0 upgrade features

• Proto Speed Control - Run locomotives at constant speeds up and down grades, through curves with and without loads, regardless of track conditions.

• Proto-Coupler Operation - Uncouple your train at any time in conventional and command modes.

• Variable Proto-Smoke Control - Control diesel and steam smoke output with four different settings (requires a fan driven smoke unit).

• Protosound 2.0 Digital Sound & Control Effects - Full Command control features and CD-like quality.

• Software Upgradeable Design - Enhance locomotives with new features or sounds as they are created.

Atlas O Diesel Locomotives

Atlas O Diesels are pretty standard, however, at the present time we are unable to convert the very early Atlas locomotives with a horizontal motor and gear towers. (Nor can we convert the SW series switcher locomotives!) Providing the locomotive has twin vertical can motors TAStudios can upgrade the locomotive to Protosounds 2.0 and even add a fan driven smoke unit!

Special Attention for Accurate Control

Protosounds 2.0 electronics require a precise combination of variables for the accurate performance of the speed control portion and chuff rate on all locomotives. While most Atlas O diesels have a standard gear ratio and flywheel diameter, there are different wheel diameters on some of their diesel locomotives, which present a problem for the normal Protosounds 2.0 upgrade kit flywheel stripes. TAStudios takes the time calculate all of these variables and to develop and print the correctly spaced flywheel tapes to match the speed step performance of a factory equipped Protosounds 2.0 locomotive. This extra step ensures your locomotive produces an accurate 4 chuffs per revolution of the drivers and complete lash up compatibility with other MTH locomotives. This step is often overlooked in the conversion of non-MTH locomotives!
