Why is this mod:

• Aesthetics. pY's train sprites are pretty kewl looking but crucially miss elevated rails support and look pretty goofy when traversing ramps;

• UPS saving. When using pY Cranes mod (to minimize the overall amount of inserter entities) due to t2/t4 wagons having 3x2 dimensions a player would need to double the amount of inserter cranes on every train station when inserter UPS cost has been reported to be one of the most impactful on the overhaul's technical performance later on. Two times less wagons means two times less of inserter entities.

• When Train Upgrader mod gets updated it'll make upgrading your train fleet much much easier (since they all will have the same size)

To ease the differentiation between tiers all changed items were renamed into Locomotive/Cargo wagon/Fluid wagon MK02/03/04 instead of Advanced/Nexelit Floating/yada-yada. Icons were changed to the vanilla looking ones as well.

This mod doesn't provide any cheaty gameplay advantages as new t2/t4 6x2 wagons are given twice the attributes of the original 3x2 pY wagons. For example, the 6x2 wagon is 2 times longer and therefore has 2 times the inventory space of the 3x2 one but the recipe is 2 times more expensive, it's 2 times heavier, etc.

P.S. This mod must be installed before any t2-4 locomotives or wagons are placed on the game surface otherwise they'll require to be deconstructed and put back to properly work. Same goes for removing the mod after placing any of the changed transport.
