What is a cdr?

"c is a list cell with a == cdr(c) and b == car(c)" --(this comment by Anka at 05:42, 20 Sep 2006 UTC; please sign your comments with ~~~~)

It's a Lisp term; it refers to the entire list apart from its first element. car refers to the first element of the list. Historically, they're acronyms for Content of Decrement Register and Content of Address Register. ais523 07:56, 20 Sep 2006 (UTC)

I have an Ackermann function implementation but I don't know how to format it or anything. Rail is awesome. I had a lot of fun writing it.

Looks perfectly well formatted to me, so I transferred it to the main article. --Ørjan 07:35, 19 May 2007 (UTC)

The description for '*' sounds wrong. shouldn't it allow the train to leave in the same direction? --heretic 04:02, 31 December 2008 (UTC)

Probably, although it sounded slightly ambiguous as it was. I think it is clearer to change a preposition, so I did that. --Ørjan 19:58, 31 December 2008 (UTC)
