Running very slowly, presumably because of a permanent way restriction, 153333 approaches Millbrook on 21 April 2010 with the 09:33 Bedford to Bletchley London Midland service. Just before the train came into view a Cuckoo was calling from the large tree on the right - conclusive proof that spring has arrived. And yes, that really is a wooden mock of a biplane on the right! I'm not sure what the purpose of it is, presumably just to confuse rail passengers and give them something to talk about!
