Step 5. Modify the Tender or Body Shell
In the case of a steam locomotive, you will probably be mounting the speaker
facing down on the tender floor or facing up in the coalbunker. You may
need to cut an opening in the tender floor for the speaker. A series of small
holes can be easily drilled and will work as well as one large hole provided
the open area is at least one half the area of the speaker cone. In either
case, there should be no openings outside or larger than the speaker cone
itself. If the locomotive is plastic and you will be drilling holes in the coal load,
drill them at slight angles and they will appear nearly invisible.
