If you want 4 character towns, change the unpack line to this: 
    my ($from, $dept, $to, $arr) = unpack('x23a4x2a4x3a4x1a4', $_);

unpack is different from regular expressions. The xn skips over characters, the an captures the character string: 
x23: skip 23 characters
a4: get 4 characters
x2: skip 2
a4: get 4
...

The 4 a4 unpack directives capture the 4 parts of the string you are interested in. Add this to strip the extra spaces: 
    s/\s+//g for ($from, $dept, $to, $arr);

Here's the whole thing: 
#!/usr/bin/perl
use warnings;
use strict;
do { $_ = <> } until /Bus Timetable/;
<> for (1..3); # skip titles 3 lines
while (<>)
{
    last if /^\+/;
    my ($from, $dept, $to, $arr) = unpack('x23a4x2a4x3a4x1a4', $_);
    s/\s+//g for ($from, $dept, $to, $arr);
    print "$from$dept:$to$arr\n";
}
