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’s reactive DDE automatically adjusts the speed, timbre and volume of the exhaust as your engine works harder while Hyperdrive2™ technology results in smooth and precise locomotive operation, even at super-slow speeds. The switching mode will add a new level of realism for those whose primary ‘fun’ is in the running! Tsunami2 TSU-1100 The TSU-1100 is a universal-style, 1 Amp sound decoder with 4 function outputs.
