Tenshodo Brass SD24 with 24 volt motor and 15 inch radius track

HO Scale Brass Tenshodo SD24 has been rebuilt with a 24 volt super strong earth magnet motor. All wheel power pickup has been achieved and now we are going to test it on 15 inch radius track. Yes you read that correctly, 15 inch radius over open space above a bare concrete floor. Nothing like this has ever been attempted in the history of collecting brass locomotives.
