To run the USA Trains UNION PACIFIC “BIG BOY” on a track, you need:
1. Track Power Supply – The locomotive operates on direct track voltage and should not exceed 24V DC.
2. Magnets for Whistle and Bell Activation – These must be placed inside the track rails to trigger the reed switches on the locomotive.
3. Properly Assembled Track – Ensure the track is correctly laid out and powered for smooth operation.
4. Lubrication Maintenance – Regular gearbox lubrication is recommended after every 100 hours of operation.
5. Optional Decoder Installation – If desired, you can install a decoder to control motors and lights, but the sound and smoke units remain connected to track power.
