Abt switch

The Abt switch is a kind of railway switch used on funiculars (inclined cable railways) that doesn’t have any moving parts. It allows two cars to pass each other going uphill/downhill while sharing the same tracks. While most train switches rely on physically moving a section of track so the train goes one way or the other, the abt switch doesn’t move at all. Instead each carriage has a grooved wheel which makes it turn left or right at a junction by sticking to the track on one side.

    I had low iron from too many donations too, at the time I was still eating meat so it wasn’t so hard to build back along with some iron supplementation.

    Iron is a weird one if youre vegan because theres a bunch of compounds in plants that can mess with iron absorption, but you should be able to overcome that by supplementing at the right time. Also yeah coffee and tea can fuck with iron absorption, tragic (just eat the iron rich foods well before or after coffe/tea). You also might need B12 supplements (unless youre trying, a lot of people on a vegan diet have a hard time reaching the right B12 levels), luckily they fortify a lot of food with it like nutritional yeast. Some lentils are plenty rich in iron, lots of other foods are. If you need a few rounds of IV iron sucrose, that sucks but you wouldnt be the first! When I worked peds soooo many teens needed it lol.

      I like barely opening my eyes and having some caffeine, now I have to barely open my eyes and have orange juice and whatever I find that looks appealing that isn’t ultrafortifed with calcium. No idea on vitamin B12 my financial and energy budget’s been lots of cheap nonperishable crap, pasta, pasta in a can, beans, potatoes, sandwiches, etc. Yesterday I bought a cabbage and chain made cabbage pancakes with flax, I know those are safe and they keep in the freezer for when I have 0 energy.

      A while ago I was eating enough nutritional yeast just for the flavor of it that my blood tests said excess b12 and my urine was neon so I had to cut back on it ooooooooooooooh
