They are no longer listed in the 2013 catalog. :-[
Dear WKT,
We can't make every model every year, E-7s are readily available from dealers; we will rerun them when the supply dwindles.
Have fun!

Thank you! It's good to hear that E7's will be back. I have three sets of E7's: Illinois Central, Union Pacific, and Chesapeake & Ohio.
I have two sets of them in Southern and just love them. I bet that when they come back again they will have the new sound system. ;)
