Traxxas Wheel Hubs, Hex (4) Wheels Hubs

The GP30's were designed to compete with GE's U25B.

The U25B offered 2500 horsepower, while the existing EMD GP20 was only rated at 2,000 hp.

The EMD's engineering department ended up using a 16 cylinder 567D3 engine that produced 2250 hp for the GP30.

They also made several improvements on the GP20 design meant to match the U25B - a sealed airtight long hood, a single central air intake, and easier access for maintenance.

These changes required more space behind the cab, and this was achieved vertically by raising the height of the locomotive, providing space for the central air system, the turbocharger, and electrical cabinet.

This increased height meant a new body was required. EMD wanted the new body to be modern and updated, so the GM Automotive Styling Center created the GP30's unique "hump" and cab roof profile.In their first production, Broadway Limited is modeling eleven railroads and twelve distinct paint schemes - all models with prototypically accurate road numbers and paint schemes.

Each model has the newest Paragon4 Sound/DC/DCC control system featuring Rolling Thunder, and equipped with integral GoPack capacitor packs.

All of the models have road-specific details and lighting.
