Here are some more links about Trolley Problems, especially concerning neuroethics, courtesy of Alyosha (alyosha@bostoncoop.net):
Here are annotated links to start you out on the neuroethics of the
trolley problems (plus a humor piece to reward you for reading to the
end!). I'm on a roll so there are several, not because i'm geeking out,
but.....to suit the taste of different readers; yeh, that's it! If you
get hooked and want even more, i've got em.
A teensy intro the to most-discussed research is here:
http://www.wjh.harvard.edu/~jgreene/
The gist is that Greene et al find separate brain modules relating to
deontological and consequentialist approaches to ethics, and use fMRI
scans to watch them during trolley problems.
Right off the bat here are a couple of critiques:

http://scienceblogs.com/mixingmemory/2008/01/cognitive_load_and_moral_judgm.php
But before i go too far with that, the other thing i wanted to bring up
is evidence from people with damage to the ventromedial frontal cortex
("VM patients"). These folks have been found to be lacking in the
deontological modules, and so act like pure(r) consequentialists.
Unfortunately, the best short treatments i found are in googlebooks. So
go to these:

http://books.google.com/books?id=EHlPFgatpYoC\
, and search for "vm", and it'll take you there, right before the
trolley stuff. Nice short treatments.
And i can't resist this not-so-trolleyish but very trolley-applicable
famous theory of five moral modules, which have been assimilated to the
neuroethics / evoultionary psycholocgy frameworks:

But you might want to back up. Here are two pieces on neuroethics more
generally. This one from Greene doesn't deal with trolleys but is a
nice intro:

; while this much longer one from pinker does bring up trolley
problems, along with tons of other stuff:

Moving back to our focus, here's a nice accessible overview of the
Greene scene along with some others:

And this one brings in virtue ethics:

And finally, here's a philosophical spoof of the trolley problems that
i find really funny:
