Listen . . .you can hear the locomotive approaching the station, a steady chuffing keeping up an even cadence. As the engine gets closer, the chuffing gets louder and the wail of the grade crossing whistle can be heard. The engine drops its speed and the engineer (you) rings the bell to clear the tracks. Bringing the engine to a stop, the engineer blows down the cylinders and lets out a short 'toot' to let everyone know the train has stopped. Your fireman, Fred, takes care of the firebox, shoveling some coal and then hops out to grease the valve gear while the passengers disembark. Three short toots to warn all that you intend to back up, then ease the locomotive into reverse to couple to the mail car waiting on the siding . . . Ka-Klank!   The airpumps will automatically pick up the pace, building up the pressure in the lines once more. This is the kind of realism that makes you wonder, 'Are these really just models?'

SoundTraxx Sierra’s unique polyphonic sound processor allows you to activate various sound effects without interrupting or interfering with other sounds. Some 'sound systems' only allow you to 'play' one sound at a time. Not so with Sierra. Activate one sound or all the sounds - it won’t skip a beat. Sierra’s sound effects aren’t just simple playback loops. Each effect is interactive and will respond to you, the engineer, just like the prototype. The airpumps, for example, will increase speed, building up pressure as the braking effort is applied. Whistle and airhorn signals for stop, reverse, forward and grade crossing, will activate as appropriate for the engine’s direction of travel. You won’t believe how incredibly alive your locomotive will become!

Each SoundTraxx Sierra is specific to prototype, meaning you get exactly what you expect . . . the real sounds from actual engines, including such classic roads as DRGW, Santa Fe, Southern Pacific, Union Pacific, and more.
