If the light light up in both derictions the diode is no good anymore.
This is true when you test with a D.C. power source. Most of our trains have A.C. power sources. With an AC source the lamp will light regardless of the direction, even with a good diode.

On the original Postwar 362 barrel loader, it would not matter which way the diode is installed.
