Bachmann C-19 Overview: Nice looking and running model. It has the Bachmann version of the Aristo "plug and play" socket. The socket is in the tender, and it is indeed a 10 second process, but be SURE to set the switches the right way: There are 4 switches: motor (ON) polarity (makes no difference on DCC operation) pickup (TRACK) VERY IMPORTANT chuff (4) 4 is prototypical The speaker in the tender is weak, it distorts easily. There is not a lot of room to add a bigger speaker, but bigger is not necessarily better in speakers, looking at a Visaton with better bass response. Also there is buzzing from the tender at certain frequencies, when/if I figure out what is vibrating, I will post here.
