More questions.
Question 6. Is there a parts list for the Vision Reefer sets (item numbers 6-81142, 6-83545, and 6-83549)?
Question 7. When TMCC 1 and TMCC 2 (Legacy) engines are having signal problems (as evidenced by flickering headlights) there is a trick called the "hand trick" which is when you hold your hand right above the locomotive with signal problems, it temporarily regains signal. Why does this trick work? (I tried to be as descriptive as possible.)
As a side note, I seem to have monopolized the question section of this thread. Sorry about that.
