Go for it, I've run out of my rail building motivation and supplies.
Yeah, I don't have the supplies right now either, specifically gold. Will need to do some mining. I did a crapload of mining yesterday but only found like three measly blocks
I wish there was an enchantment that increased the drops you got from iron and gold ore blocks.
Incidentally, enchantments are like . . . pretty broken.
Here are two enchantments I got yesterday on some diamond tools:
1. Efficiency II
2. Efficiency I + Unbreaking I
Guess how much each one of them cost?
I would say that #2 was the better deal. It ended up costing me 2 levels. The first enchantment cost me 18 levels. Why is that really possible? There should be minimum values for different levels.
Heck at 8 levels of investment I've gotten Efficiency II, Unbreaking II. I think that was maybe bit of a fluke but it's happened more than once and is much better than the 18 levels I spent.
Second time around I spent 30 levels and got Efficiency IV, Unbreaking III and Fortune III so at least I didn't get burned twice.

Anyway I don't know how long I'll have the motivation to build rail either. Usually I play a lot of minecraft for a while and then drop it for 6 months. I'll try to at least put a tower near the end of your rail, more or less.
