The adjustable steam cutoff is guaranteed to make you feel like you are in the cab and in control! Drop into Drift Mode and listen to the rod clank and valve packing effects.

Fireman Fred has a few new things up his sleeve as well, as he works to keep the locomotive in prime operating condition.

Selectable fuel loading makes models sound as they should, from hand-shoveled steam engines, to oil-burners to those equipped with augers, to wood being stacked.

Tsunami2 Diesel decoder's 50+ sound effects and expansive sound library includes engine startup and shutdown, engine prime mover through all eight notches, straight-to-8,

HEP mode, 13 bells, over 40 airhorns, 4 air compressors, dynamic brakes, radiator fans, brake squeal and more.

Tsunami2 goes several steps beyond ordinary sound generators. Whether steam, diesel or electric, Tsunami2 is so powerful that it comes with four special effects processors - the Equalizer, Sound Mixer, Dynamic Digital Exhaust and Reverb. It's
like having a complete sound studio at your fingertips! Each and every sound can be independently set for the volume that suits your ear.
