According to Google maps and sbb.ch, the most closer railroad station is Alpiglen:
. According sattelite map, you'll get beautiful view from there.  

Not sure where are you getting from to the Eiger, so you can search trains by youself.
If you have more specific information, please provide it.



Update:
According oebb.at, route and prices are (used local time just for example):  


30.06.11 Stainach-Irdning 09:37 - Bischofshofen 10:48 - from 15.70 euro for 2d class without VORTEILScard
30.06.11 Bischofshofen 11:08 - Mannheim Hbf 16:56 - from 106.80 euro for 2d class without VORTEAILScard
30.06.11 Mannheim Hbf 17:36 - Interlaken Ost 21:56 - unknown by oebb.at, unfortunately, but by http://bahn.de - from 95.60 euro for 2d class
01.07.11 Interlaken Ost 06:04 - Grindelwald 06:38 - unknown by oebb.at, unfortunately, but by http://sbb.ch - from CHF 5.20 (near 4.4 euro) for 2d class
01.07.11 Grindelwald 07:17 - Alpiglen 07:38 - unknown by oebb.at, unfortunately, and by http://sbb.ch there is a bug with no founded station, but I think it is not very expensive


Also you can see [this question][11] to get some more sites to search prices and trains.

How can I get to view the North Face of the Eiger in Switzerland?
The question is in the title: from what I read in the answer to another question, Artin L-functions are conjecturally cuspidal automorphic L-functions for some algebraic group that can be transfered to $GL_{n}$. On the other hand, elements of the Selberg class are widely believed to be (cuspidal?) automorphic L-functions for $GL_{n}$. So where exactly lies the difference between those two sets of L-functions?
Thanks in advance.
