Train Miniatures first FA-1 Freight Diesel was made in Japan by Micro Cast (Mizuno)
Released and distributed in America by Train Miniature of Illinois in late 1970 and reviewed in the October 1970 edition of Model Railroader.
The September release was a powered FA-1 dummy FB-1 retailing at $17.98 for the A-B set.
The Company was acquired by Walthers in 1984 and the original Micro Cast FA-1 FB-1 Locomotive shell casts with updated shell modifications and new chassis and drive mechanisms became the basis for Walthers FA-FB-1 locomotives under the Train Line Series.
The original Train Miniature FA1 FB1 release in 1970 had a really nice shell for the period, but the drive was an abomination, the frame was formed sheet steel, not sure what the gear ratio was, but the motor was a 1/32 Strombecker (Hemi) slot car motor, no flywheels, slot cars which are extremly light and normally run like 30:1 high RPM’s
The TM Loco drive ratio didn’t permit the motor to get anywhere near it’s power curve.
As a result the TM FA-1 ran really smooth and quite more so than any other HO diesel on the market at the time. It had a top speed of about 15 MPH, and that was reduced dramatically to 6 MPH with a 5 car freight train behind it and then to zero quickly once the motor then overheated.
Believe it or not the motor got hot enough to burn the skin right of your fingertips.
Many removed or never installed the screw in block weights that came with the Train Miniature FA-1 as the Loco would tilt that way, or this way depending on it’s direction.
The drivers were about 46" tall, not 40" the frames were hard to work with. The whole Loco was made by Micro Cast (Muzino) of Tokyo Japan. The nylon gears were also prone to cracking.
Train Miniature in 1979 did a clone of Athearns F7 cast metal chassis which was fitted with Athearns non Flywheel Jet 400 motor Athearn Part 4001 and Athearn Trucks from Athea
