YMMV / The Railway Series B22 "Small Railway Engines"

• Harsher in Hindsight: The source for the new weed-controlling ballast that makes even the tender engines comfortable going into sidings? The waste mounds at a shuttered lead mine. One can only wonder if the Fat Controller ended up with a big environmental cleanup bill on his hands.
• Hilarious in Hindsight: In "Useful Railway", Rex describes clothing as "what people wear instead of paint". This adds an extra layer to "Henry Sees Red", suggesting that pulling a train only in undercoat would be the same as a person working in their underwear.
