Model Railroading > Speedometer

This looks like a fun product. Does anyone have one of these and can you tell me how well it works. At our club it would be great to mount this inside a tunnel and send the output to the cabs.

*** From the TTX website ***
The Scale Speedometer is designed to measure the scale speed of a model train either HO or N Gauge in MPH or KPH. Great accuracy is achieved through the use of quartz crystal timing and a microprocessor for performing the calculations.

The unit has built-in sensors so no installation is required, the speedometer is simply placed over the tracks so the train will pass between the box and the reflector. When the train breaks the first beam the unit begins counting. After the second sensor detects the train's passage the microprocessor calculates and then displays the scale speed. The speed is displayed for 7 seconds then if the train and cars are clear of the speedometer the unit will automatically reset and wait for the next train. If the train has not passed through in 7 seconds the speedometer monitors the trains passage and will not reset until the last car has passed by.

The speedometer has a very wide range reading as low as .3 MPH up to over 900 MPH. The accuracy is better than .25 % at 50 MPH.

The speedometer is powered by a 9 V battery making it portable.

What's the cost? ;)

I saw one at a trainshow and it was real crowd plaeser. I think it is a great idea for those who like to have a little fun.

A little steep at $65.00 US, but it has potential. A remote feed via hard wiring(?) or one of those X10 micro cameras aimed at the speedo linked to a video terminal would certainly interest visitors.

Just what every HO scale weed weasel needs.... >:O) Do they throw in a camoflauged Train Master with a shrub on his head like Bu=ill Murray in "Caddyshack"????

I belong to the Nashua Valley Model RR club in Bolton,Ma and we have one of these in use , it is a great tool for users of DCC (we use North Coast Engineering) it helps for scaling the speed for realistic trains.
