I never really got too much into any of the cart/train mods myself. Minecraft just doesn't have any resources vast enough to warrant setting up a track and stations to move around. What I mean is, there's little point in spending three hours building a rail track to haul oil from a well that will deplete in an hour. Now if there was a "realistic" source of something that could last for days or weeks, that could be something worth investing in. As far as moving carts through portals, if you're doing that, might as well just use enderchests or teleport pipes.
One mod I can't imagine playing MC without is InvTweaks. Even when playing vanilla I always install it. Moving all items at the same time or automatically sorting inventories is simply priceless.
