2009年7月14日 · The HT-B truck was used on 3500 hp BB prototypes at a time when many railroads thought even 3000 hp needed six axles (witness the popularity of the SD40-2 versus SD45-2). So, at a guess, the new truck design offered higher adhesion.

The HTB® LT — Lightweight, non-torque reactive rear air suspension system combines superior ride, improved stability, reduced weight and reduced maintenance. Unique design and com-ponents make the HTB LT reliable and rugged, as well as the lightest suspension in its class.

Hendrickson's lightweight, non-torque reactive HTB® rear mechanical suspension system combines excellent ride and stability with reduced weight and scheduled maintenance. The parallelogram design controls suspension windup and corresponding frame rise, while reducing suspension induced driveline vibration for extended driveline component life ...

Weighing up to 275 pounds less than a typical 40,000-pound capacity suspension, Hendrickson's HTB ® LT sets a new weight standard for drive-axle suspensions. The patented, non-torque reactive design helps deliver quiet, smooth operation with today’s high-torque engines without any torque restrictions.

The HTB LT rear suspension can be visually inspected by checking for lateral offset, checking for component interference, looking at the air spring, and looking at the torque box and the torque box bushings.

IIRC the HTB truck came out of the cooperation of GM and ASEA in the early '70s (compare the trucks on the GM10B electric). I've always understood it as a zero-weight-transfer, high-adhesion design, not something optimized for ride or tracking quality.

2009年3月23日 · It is just two rigid two axle trucks connected by a span bolster for vertical load transfer, a low mounted traction linkage to minimize weight shift, and a patented interlink between the two 2-axle trucks that improves the leading axles angles of attack to the rail.

2008年12月21日 · Swimming in a sea of Action Red... I cant believe with how good Athearn's stuff looks above the frame, how BAD it looks below the frame! Word on the street is that their upcoming releases will feature more frame detail. why am i wasting my life on N scale? damn that's awesome. How long will it be before they show us how to add DCC to a tree?
