If I could find a couple of '11xx' shark fin Scouts that actually ran, maybe. Otherwise, no, not on purpose.
Of course, there was the incident on the South Hills Shopping Center layout when TMCC first came out. We were demoing two trains operating independently on the same track, and discovered the chicken wire used to hold up one mountain blocked the TMCC signal. So the loco kept going when it was supposed to stop, then reverse direction to avoid a collision. Ooops!
