Note For Southern Pacific GS4 Locomotive:

While the GS4 operates well in DC mode, we (Kato) understand there is an issue with the use of DCC in the GS4 locomotive.

To prevent damage to the locomotive and decoders, we ask that customers DO NOT install decoders in their locomotives and to NOT operate them on DCC until we announce a correction to this issue in the very near future. 

We apologize for the inconvenience this may cause some of our customers.

We will resolve this issue in a timely and effective manner.

Thank you for your understanding and support.Best regards,  

Tadashi NamaAsst. Vice President
