Setting it up couldn't be
easier. Simply connect the TT300 Digital Point Motor to the programming
track and assign a value to CV1. This is the point motor address. Then using
your DCC controller set up the point at that address in the usual way. You
can add the point to a route or switch it individually as required.

So how does this product stack
up against other available solutions?

A similar concept to the Traintronics TT300 Digital Point Motor
is the Viessmann 4554 switch
that also incorporates an accessory decoder and can be used on DC or DCC
layouts ( as well as Märklin / Motorola, NMRA-DCC und Märklin Systems). The Viessmann
4554 switch motor sits above the baseboards next to the point and would work with modern
layouts as it resembles a modern switch box. It wouldn't really work for
classic layouts unless you somehow hid the mechanism. The
manufacturer price for the Viessmann 4554 switch motor is £32.59.

And how does the price work
out with the built-in DCC decoder compared to conventional point motors and
an external accessory decoder?

The Tillig 86112 is a standard
point slow-action motor. The manufacturer price for the Tillig 86112 is £13.81.

The Lenz LS150 is a common DCC
decoder with 6 outputs. The manufacturer price for the
Lenz LS150 is £40.99.

So you may think that a
built-in decoder might me an expensive option. The table above shows that Traintronics TT300 Digital Point Motor
is a cheaper option even for 6 point motors, but it is much cheaper if you
only need a few points.


  • Reasonable price, good value.

  • Solid construction, good
    connectors and sturdy.

  • The pin is quite thick. If you
    have a fine point such as the Tillig points, you will have to enlarge the
    hole in the point throw-bar and perhaps reinforce it. Even Peco points may
    have to have the hole enlarged a little.

  • The TT300 Digital Point Motor
    is quite deep and although will be fine in most cases, may be too thick if
    used on multi-layered layouts.

  • The TT300 Digital Point Motor
    has a neat feature that keeps a gentle and constant pressure in the right
    direction at all times. Even if you force the pin the other way, it
    re-engages and moves the pin back to the correct side. Where other point
    motors like the Tillig or Flugerex motors hold the blades firmly to one side
    or the other, this system will allow a little flexibility which could
    prevent damage to the point blades. I had switched a Tillig controlled point
    by mistake when a train was over the points and the point broke due to the
    force of the motor pushing against the open blades.

  • For addressing above address
    255, CV9 has to be used in conjunction with CV1. See the manual for how to
    do that.

  • Basic route selection can be
    programmed via CVs if your DCC command station doesn't support routes.

  • The remote control feature is
    quite nice. It allows you to have a little push-button switch, say on the
    side of the layout near the point, where you can switch the point locally.
    Pressing the button will throw the point to the opposite state of where it

  • The included basic manual is
    reasonable. It would be nicer to see a better quality pamphlet
    with better photos. The advance section is not included. It is linked to
    below. Print that out and the full function of the point motor can be seen.

The full installation instruction
and operation manual for the can be seen on the Bromsgrove models site,
