My wife picked up a MTH NYC freight set for me how cool. The engine number is 5405 I believe it has a QSI sound system with electronic whistle, optionally equipped with passenger sounds squealing brakes and proto-smoke. I removed the tender shell and it has no back up battery it has a QSI double stacked board set (Whistle sound-A 96-7-31 on the PCB) it runs but takes off to full speed and the smoke unit just blows constantly and no bell. I'm just wondering if this is normal for this system,and what options might I have with the current system. Or should I upgrade to PS-2. Transformer wise I have a ZW,LW and MTH 750 and a MTH IF remote.
Thank you all for the fantastic information on this site.
