“It saves me over 20 pound per return trip. That’s incredible!” a TrainPal user commented on the Google Play Store.

The country’s railways are frequently criticized for being “the most expensive, least comfortable and the least efficient transportation system in Europe,” Daily Mail reported. In addition, crowded ticket purchase channels and floating ticket prices create an even more stressful situation for travelers.

“We provide a Chinese solution to the British customers, and it’s going better than expected,” said Amy Wei, CEO of TrainPal.

The TrainPal craze followed a recommendation on a famous British television series called “The Gadget Show.” Demand was so high at first that TrainPal’s servers crashed. It was the top app both in the UK and Ireland for the next two weeks.
