Space/Click Me Google Images Both* engines are based on a Bachmann 0-4-0 G scale side-tank porter, paired with an LGB ToyTrain tender. (The two models pair surprisingly well together - I own a set) Bluebird lore: Major accident(s), so lots of rebuilds and overhauls. Ended up just being used as the testbed for EVERYTHING, so we get this. * That's a lie. Bluebird's based on an LGB 2-4-0 but with the proportions edited to resemble the Bachmann for lore reasons, then No. 28 is based on a Lego model I made. (Which is why the pony truck exists - Porters are not conducive to balancing themselves...)
