Price: $229.99
In stock ready to ship to you

Sound and Light package for Intermountain SD40 & SD45 locomotives.. 

Please note that:  We use the LokSound Micro sound decoder not the drop in entry level sound decoders.  Everything is self contained for maxium realism and versitility.

Give your layout and running sessions the dimension of sound with TopHobby's Intermountain diesel sound and light package.  The LokSound decoder faithfully reproduces the distinctive sounds of the appropriate prime mover.  Operation of the loco is smooth and consistent through the throttle range.
