Arthur’s smile was gentle. “That one got lost in the post during the strike of ‘72. Never did find another copy.”

He had drawn the illustrations himself with coloured pencils: Thomas pulling Annie and Clarabel through a snowstorm; Gordon, proud and gleaming, on the repaired viaduct; and a final picture of a signalman, waving from a box, as an engine whistled its thanks.

Leo, now fourteen and fiercely sentimental, made it his mission. He scoured charity shops, railway museums, and online auction sites. He found digital scans, blurry PDFs of long-out-of-print stories, but they felt hollow—text without texture, words without warmth.

Leo held the binder like it was made of gold leaf.

As remembered by Arthur Penhale

“Why don’t you have them all, Granddad?” Leo asked one rainy afternoon, pointing to a gap on the shelf where Gallant Old Engine should have been.

“I can’t give you what was lost,” Arthur said, his voice a low rumble like a shunting engine. “But I can give you what I remember.”

“This is the only complete collection, Leo,” Arthur said. “There’s no PDF. There never will be. Because a story only lives when someone tells it to someone else.”

Years later, when Arthur’s signal box was decommissioned and turned into a museum, Leo donated the binder. But he kept one page—the final illustration of the signalman. And on his own laptop, in a folder named “Granddad,” he kept a single PDF file: a scan of that handwritten collection, shared only with his own children, and passed down like a driver’s watch.

On the highest shelf of the signal box, wrapped in an oilcloth to protect it from the coal dust that still lingered in the air, was his battered copy of The Railway Series . It wasn’t a single volume, but a collection of the original small books— The Three Railway Engines , Thomas the Tank Engine , James the Red Engine —each one a treasure he’d saved his wages to buy as a boy in the 1950s.

The file was small. The story was not. And somewhere, on a distant branch line in the sky, Arthur Penhale leaned out of his signal box, pulled the lever, and gave the right of way to a train that never stopped running.

Arthur Penhale had been a signalman on the North Western Railway for forty-seven years. He had watched steam give way to diesel, watched engines come and go, and watched generations of children press their noses against the cold glass of the booking office, hoping to glimpse a flash of blue or red on the main line. But his truest companions were the books.
