The very first model railroad throttle which was mine was the Troller TRA-1000 that my Dad gave me for Christmas or my Birthday one year.. I think Christmas. It was also the first hi-tech Transistorized throttle I had, complete with Momentum and a Brake to simulate real railroad operations, and smooth control.
Wow! -- And I still get that feeling whenever I use mine!
Troller had some problems with under-building their units or selecting parts that had a higher failure rate (obviously not on purpose)... and had to repair so many units, that I think that drove them out of business.
Which is a shame; while simpler, their throttles were easy to use, compact, and let you operate more realistically.
Before they shutdown, Troller even introduced some newer throttles like the AutoPulse series, which enabled pulse power automatically like a TAT to improve locomotive control in all speeds and conditions.
I wouldn't mind a second TRA-1000 as a backup.
Later, when I started modelling O Scale 2-rail, I stumbled across the TRH-200 hand-held cab-control version of the TRA-1000; a perfect way to have walk-around throttle for switching, and etc.
My very first throttle was a transistor throttle, a Troller TRA-1000 with momentum and braking. Pretty cool, let me tell you, when my Dad got it for me as a Christmas Present.
It worked great, and then it died all too quickly (in a few months) one day.....
My Dad sent it off to Troller, and they returned it fixed after a month or three.
It turns out that Troller had a problem with their Darlington output transistors, and even nice use of it ... could result in a blown transistor. Oops.
I really missed it while it was away, very awesome to see trains slowly accelerate, and be able to brake them like you handle a real train -- not like Jack Rabbit Engineer on the throttle!
Years later, when I had my house, it went with me so I could "play trains" when I was away -- all the other throttles were my Dads'.
This is a hand-held Cab Control throttle, powered by low voltage. No built-in power supply; it gets power from a power pack.
It's just a nice little Momentum + Braking cab control that is a simple compact version of a TRA-1000.
One cool feature is that it can run from either low voltage AC or DC power.
Yes and the TRH-200 has the same Darlington output transistor problem as the TRA-1000!
