How much battery could be stuffed in one Eggliner?
I think it would be neat to have sensors on both ends that would govern the speed... including stop and/or reverse the motor if some object (another Eggliner!) got too close, so that I could just turn the fleet loose on the track... I have a short section of bi-directional single track between my loopbacks that would be fun to watch a fleet of them try to avoid each other in!





Well, my G-Scale Graphics "RailBot" does just that. They operate very close to your description above, with the exception of no reverse. I usually run one full size train under Critter or RailBoss control, and then put a couple of RailBots out to cruise around on the same loop of track.

I was thinkin' I had seen something like that, but, for "my" layout, I would HAVE to have a reversing of the motor on at least some of the cars. I have cogitated on this automation for quite some time (not in just about the Eggliner, but any trains) and that short section of bidirectional track is a real problem... if two cars eventually meet on it all of them stop in just a few seconds. If one of the two that cause it can be reversed then the only problem is if any part of the train is still in the "Slip-switch" at the exit of the loopback. An Eggliner reduces the chance of backing into a switch with half the train on the diverging route and the switch set the other way. (Ya just don't wanna split a train over a switch!)

Each car would have to have a predeliction to go forward and that strength of that predeliction would have to be varied amongst the cars... each car has a different priority compared to the others. So if two cars meet head-on on the single track one will reverse and the other will just slow (or stop and wait for the other to get farther away) until the way is clear to speed up.

Of course that means that the car that reversed will have to go all the way around the loopback and then traverse it again forward before it could proceed to the other end and it might have trouble doing that if the car that is "pushing" it backwards is too close for it to decide to go forward again... might end up with all the cars being pushed backward by the highest priority car or the lowest priority car stuck between two higher priority cars coming into the single track from opposite directions.

It is a puzzle that may not be solvable by standalone brains in each car. It would probably require some communication between the cars or a variable priority based on where the car is or is going or knowledge of where the other cars are at all times.

I will not rest content until I see pantographs on an eggliner.


A thought just occurred to me: where's the ca 1850 Eggliner? Hmm? I feel my area of interest is being ignored!

Ummmm... wouldn't that, today, be called a "Bobber Caboose"?
