The TCS-A4X is designed to be a drop-in/solder-in decoder for locos that have the traditional Atlas/Kato PC light board. Its shape is like those boards so it is a replacement fit. While this board can be easily installed in any loco with the Atlas-style board without soldering, installation in locos with the Kato-style board will require at least a minimum amount of soldering.
