The NTSB (National Transportation Safety Board) and the ARRDOA (American Rail Road Dumb Operaters Association) approached me about conducting a test to observe the effects of gravity on certain engines, and report back to the users on this forum. As a service to those on here, I volunteered my services.

 

I chose to use an MTH 2-8-0 that came from a set. The engine was dropped from the end of a platform at a height of 28" onto concrete to see what the effects would be. I am happy to report that the only results of the test were compression of the dummy front coupler ( see photo) and a small chip on the stack (see other photo.)

 

The drawbar suffered a slight bend when the engine pulled the tender off of the board when the test was conducted. That was easily straightened out, and the electronics, sounds, lights and drive train worked perfectly after said test. No further results were gathered, as it was ascertained that the strain of this test was all that said tester could endure.

 

In order to not appear so stupid as to deliberately run such a test, the tester decided to run his train, and check a turn out while the train continued on to another turn out, thrown for the curve....or so the tester thought. To run the test, the tester feigned that he did not know the thing was actually set for....wait for it, straight!

 

Both agencies suggested that I put this disclaimer regarding the test: It should be noted that it is not advised for the novice runner to duplicate this test. Results may vary with user, engine, table height - and landing material.

(Did I mention in another post that I installed my first "lift out -hinge up" into my temporary Christmas layout this year??!! ;-> If you use one, follow the advice of others to put a kill switch in it so that this will NOT happen to you.)

A locomotive falling to the floor has always been a thought that sends chills up my spine.  When I built my layout, I included a lift out bridge on the branch line so I could access the room.  I included electrical contacts in the bridge structure so that when the bridge is removed it kills the power to approximately three feet of track on either side of the opening.  There is no way I can run a locomotive off the end of the track, even if I have a massive brain fart. 

 

I'm glad you had so little damage.  Thanks for sharing your experience.

I have seen a Lionel GP38 that was tested from 4 feet onto a wood floor. The backshop crew had to use superglue to repair the front of the engine around the coupler area. The backshop had her up and running in a day.  The railroad started using a brick on the track about 1 foot before the end til the earth and track were built, this stopped all future fall testing.

A brick would have worked for me (I would have needed 4 of them) IF I thought I would have been dumb enough to have done what I did!!

 

It this were a permanent layout, instead of a temp/Christmas one, I can seek how easy it would be to fix the problem. I ran wires to the track on the lift up to power the tracks, and those wired got power from a few feet away from the gate.

 

I could have cut the power/insulated the track for 2 feet on either side of the opening, feed power to the lift up, and had a copper contact come down and touch another copper contact which was then wired to the 2 foot section on either side of the opening, just like Tom detailed. (Glad you were smarter than I was !)

 

Thus, when the gate was up, no contact was made (even though the gate track was hot) until it was lowered, which then feed power to the main tracks 2 feet on either side of the opening. I knew what to do in the beginning, but discounted doing it, never dreaming that I would do something I knew I would not possibly do....run and engine off the track into the hole, finding the floor! I am sure I am not the first.

 

Live and learn....well, learn sometimes. Greg
