Model 847-860
Siberian Express® PRO PLUS
12-Volt 152 Decibels 

SIBERIAN EXPRESS PRO PLUS is engineered with the latest technology using reinforced ABS plastic; the sound produced by the three trumpets is incredible! Using reinforced ABS plastic significantly decreases the overall weight of the horn. The reduced weight makes installation easier, ensures less vibration and eliminates the need for extra support brackets to prevent damage to the horn when driving on rough roads. The trumpets are finished with an attractive semi gloss black finish and the steel-mounting base is painted silver to help prevent rusting. Wolo is the originator of the ABS plastic train horn SIBERIAN EXPRESS PRO PLUS; so don't settle for cheap imitations. SIBERIAN EXPRESS PRO PLUS comes with a built-in heavy-duty 12-volt electric solenoid.

The on-board air system provided is designed to produce a large volume of high-pressure air to power the SIBERIAN EXPRESS PRO PLUS TRAIN HORN and includes everything necessary for a professional installation. The extra heavy-duty 12-volt motor of the compressor is balanced to precision, and there are 4 heavy rubber bushings mounted into the base virtually eliminating all vibration. The pump produces 3.5 CFM for quick air recovery to the storage tank. For easy installation there is an extended length stainless steel high-pressure hose that allows the compressor to be surface mounted, the stainless steel hose connects the compressor to the 5-gallon metal air storage tank. Other features of the SIBERIAN EXPRESS PRO PLUS are; the tank has a built-in pressure switch, manual water drain, pressure gauge, pressure relief valve and brass fittings. Kit comes with mounting hardware, 10 ft. of flexible high-pressure hose and 20 ft. coiled filler hose with quality brass fittings.
