You need a controller with two throttles.

You'll need a second DCC controller, such as Bachmann's 'Walk-Around Companion'.

It's currently sold out on the Bachmann site, but it's available at a number of on-line retailers.

You may want to wait for the E-Z Command Smart Interface. The replacement for the discontinued Walk-Around Companion.
