Upgrade MTH 20-3021-1 UP Big Boy


Big Boy with aux tender

This 1997 Big Boy was my first "big steam" and inspired me to knock out basement walls for my current Run Room.  It was also my first PS2 Upgrade done in September of 2004.

Tender Upgrade Completed

The kit components placement and wire management are easier in a large tender.  Both tender and water tender lights light for Backup.  Wire management is critical to prevent shorts that destroy electronics.
