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.)
