security in a city does make a big difference and if you do panel you would know that no matter how hard or easy a train is to hit, its all about producing something to the best of your ability, and to the quickest of your ability, depending on the circumstances you find your self in example yard , lay up etc... as for Sydney i freaked out when i saw the yards its soo much different to Melbourne but then again double-decker panels look shit if their not t2b's so doesn't matter
