Cargo wagons which can directly request items from, and provide items to, the logistic network. Configure items to request and provide at each station for each logistic cargo wagon, allowing flexibility in unloading on curves, changing train length easily without building infrastructure, and further boost loading and unloading rate through robot speed research.
Nuclear powered robots that don't need to recharge. Forked from Buggi's Nuclear Bots and changed to have a more balanced formula, not have 3x the speed of normal bots, fire immunity, and some acid resistance for construction bots. Finally a use for all that Uranium that piles up! The recipie was scaled to require as much energy as a normal bot would use in 21 years - about the same time that a nuclear submarine reactor core lasts.
