High Speed Rails?

[nop277]

I must be missing something big, because I have been trying at high speed rails for the past while and so far I'm running into the same wall I seem to always run into when trying to make a rail system. My minecart seem to slow down really fast, I put like 10-15 transition rail at the beginning and then even put booster track every 13 track even though someone said it would work every 37-39. The cart seems to speed up somewhat, but then I'm lucky if it makes it to the third booster and I can definitely outrun it by atleast the second booster. I'm really lost now, does anyone know a good guide? besides telling me to slow down my cart (which doesn't seem to be my problem) the wiki and other places have been rather quite useless to me.

this happened to me when i had a train, it can only really be a single cart with someone in it
