Are dogs allowed on the London underground or Heathrow Express?
Yeah, you can take dogs on both the London Underground and the Heathrow Express / Connect. If you take the Tube, you’ll be on the Piccadilly line already, which will take you to Kings Cross. From there you can take a National Express East Coast train to Glasgow Central station. If you decide to go by Heathrow Express or the Heathrow Connect (which is cheaper), you’ll come into Paddington. From there, you’ll need to transfer (presumably via the Circle / Hammersmith & City lines on the Tube) to either Euston or Kings Cross. Virgin Trains go from Euston to Glasgow aswell, so you have a choice of either KingsX or Euston. Remember, Heathrow Connect is about £7 single compared to the Heathrow Express which is about £18. The only difference is that the Connect service stops at about 5 stations in between the airport and Paddington. But as it only takes 10 minutes longer than the Express, in my mind thats money well saved.
