Atlas locos with two removable weights
There are a few different versions of the earlier Atlas design
with two weights one screwed into each end. These locos are
fun to install sound into. A 16 x 35 mm speaker will fit on top
of the rear weight once a bit over ¼ inch is removed from it.
Figure 5 shows the one-screw version of this weight after it
was milled down and a slot cut to allow the sound from the
front of the speaker to go out through the truck area. The
speaker will be attached to the top of the weight with caulk.
Hint: be careful that no caulk gets onto the speaker cone. A
similar result can be obtained with a belt sander and by drilling
2 holes ¼-inch in diameter instead of milling the slot.
Figure 6 shows an Alco RS32 with the two-screw version of
this weight. No caulk is necessary to hold the speaker here. I
