Use placeholders. Not only does it solve your quoting problem, but it prevents nearly every SQL injection attack known to man. 
my $sth = $dbh->prepare( <<__END_SQL__ );
SELECT Table1.Name
      ,Table1.Address
      ,Table1.City
      ,Table1.State
      ,Table1.ZIP
      ,Table1.Phone
  FROM Table1
 WHERE Table1.BusType = ?
__END_SQL__

foreach my $line ( @lines )
{
    $sth->execute( $line );
    # Do whatever you wanted with the executed statement, like fetch()
    $sth->finish;
}

Try it out before you discard it. This is how DBI is supposed to be used.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
