By the looks of it there isn't really much to go on in the log unfortunately. Does vanilla minecraft work? Does forge work without any mods? If it does, then add mods a couple at a time or in batches, test in between to make sure it works. If it doesn't work, back up, only add 1/2 the mods you added, keep checking. Or, hope someone sees your post that has a better suggestion!

You give up too easily, it says it right there in the log, if you read it.

That's why the switch lever name is yellow like that. Names change color based on rarity. net.minecraft.item.Rarity has the names and colors of the forge default ones, and you can add more if you'd like. I can't tell why your one way powered rail is yellow, you got me there! But I wouldn't think it's a problem if everything else works, it is just somehow defaulting to uncommon.

I think you're looking for RenderTypeLookup.setRenderLayer(Block, RenderType) in your FMLClientSetupEvent. RenderTypeLookup.setRenderLayer(ModBlocks.FIREFLOWER_BLOCK.get(), RenderType.getCutout()); is what I have for a flower i made.

To be fair this post is a year and a half old, I'm sure many MC servers are fly-by-night, here one day, gone the next!

Is your code available, preferably as a github repo? If not can you post your switch lever and one way powered rail classes in spoiler tags? *edit: I ask because in looking at some code I was tinkering with, setting an Items Rarity to Rarity.UNCOMMON will give it a yellow name like that.

I don't play with noteblocks, so I couldn't tell you if this is the fix for that or not, but there's mention of noteblocks in the forge changelog for a version newer than the one you have:

Please post your debug log as described in the EAQ. It would also help to see your code in a github repository
