There can't have been all that many people who used just that stretch of the line for their daily journey. Hounslow East often seemed a chilly, windswept station - westbound there wasn't even a shelter, just a ticket collector's hut IIRC (well, as you know, as it used to be near the end of the line, I expect few apart from you actually boarded there going westbound). It's an impressive station now, with many airport staff using it. Living in Heston, I either walked to Hounslow West, or got the 232 bus, or the 110 to Hounslow East, whichever came first (usually the 110...).
