Signals Crossed

S18 E5: CGI animated escapades with the famous little blue engine, based on the much-loved books by Rev W Awdry. Toby is always nervous when he has to go through Knapford Junction with the big gantry signal over the track. One day Toby waits nervously for his signal to change, but it stays on red. He waits and waits, holding up other engines, but the signal does not change. The Fat Controller is very cross until everybody finally realises the signal is broken.
