Birney Project ~ A Weighty Situation

Adding Weight to the Birney Car 

The weights I used are those kind that you see that come in a long strip with double sided sticky tape on one side. They are usually divided into sections that can be broken off anywhere at 1/4oz increments. They are usually available at your local model train shop for weighting freight and passenger cars to NMRA standards. I was able to fit 4 of these 1/4oz weights for a total of 1oz added weight.

Location of weights

1. Cut and fitted to clear the motor frame and filed to conform to the curve of the end of the car. Then epoxied into place under the floor.
2. Trimmed to fit under the roof in the sub roof cutout.
3. Filed to conform to the curve of the end of the car. Then epoxied into place under the floor.

Weights 1 & 3 had their double sided sticky tape removed so that they can be slid under the pilot. There they were epoxied in place. Here you can see where weight #1 was trimmed to clear the motor mount.

Weight #4 had to be fitted inside the front of the car. Yes, the car has a "front and rear" now. Originally it was designed to be double ended, but I ran into this problem. As you can see, Birney the motorman has been removed from the seat assemblies and is now fitted into the front of the car.

Weight #4 was notched to fit around Birney the motorman's seat.

The top of the weight had to be ground out to clear the headlight bulb and wires. Then it was painted black and glued into place.

After all that effort I was able to add an additional 1oz to the car bringing it to a total of just over 5oz. Doesn't sound like much but that is another 25% added to its weight. And the car is suprisingly heavy when you pick it up. Yes sir! Quiet heavy.
