My grandson recently purchased a HO GE 44 Ton switcher (Item # 62201) DCC Equipped. It has no cab # and I was told that Switchers did not have cab numbers. I personally am relatively new to DCC technology but I believe it has been set up with a primary number as it responds to 003. I would like to assign it an individual secondary number which would be specific to that particular device. I would also like to have the lights work (which they currently do not) and ideally have the ability to sound the horn. My question to you is do they have the ability to light and sound a horn out of the box or does it have to be programmed or have an additional board installed. My other DCC trains can be optioned by changing CV programming. I'm not familiar with the term DCC ON BOARD as opposed to DCC EQUIPPED but this unit has these features.
