Back in the late 90s, Lionel re-issued the Culvert twins in conventional and CC models. Being a TMCC groupie, I got the CC versions. They worked great with command control. Just give them an Engine ID and press the Boost button to activate them.
As an aside, they were purchased from the yearly Heritage Catalog. Heritage Dealers were separate from regular dealers....I'm not sure the rules (it may have been due to volume of inventory bought from Lionel)......and Heritage Catalog items come with a Heritage Lifetime Warranty.
Here they are on the old attic layout:
2003 was the last time I ran them. Then we moved cross town. I stated taking done the layout in the Fall of 2003.
The accessories were boxed and stored from 2003-2011. The new layout was started in 2011, but they have sat as statues on the layout as I slowly moved along. Today, I wired them up(temporarily) to see if they worked. They did! And they worked well!
Now, I will admit that I said a few prayers and had my toes and fingers crossed!
It's a great feeling!
