I am a new comer to the hobby. My question is, I've recently purchased several sets of Bachmann train collection from Hawnthorn Village, that including the New York Central, I do not know what type of engine this is, also can I add DCC's capability the these trains? I've found a Digitrax Zephyr Stater Set-2.5 Amp at a garage sales for $15.00. Can I add this system to my layout? Help....

Thank You
