If using contactless are the through fares from the airport the same as the fare from Parkway with an extra £4.90 added? If that is the case then the shuttle could use its own card processing for its fare with TFL charging for the journey starting/ending at the national rail barriers at Parkway...

Ticket barriers only check if somebody has a ticket valid from the station which could be to/from the closest/cheapest destination possible from the gateline. This could be a lot cheaper than a ticket to the first ungated station served by the train the announcement was made on. People...

An announcement like that could be made regardless of whether there are any revenue protection staff onboard. Passengers would still have had fair warning if they are found to be without a ticket. In areas where penalty fares can be issued on platforms as well as on trains then that should also...

The driver will be walking through the train while it is travelling to and from the sidings- passengers (people) onboard the train could cause a risk to their safety. I wonder how the Paddington platform staff will manage when some trains are terminating/reversing and others are continuing...

The SSP customer feedback website can help identify their outlets. Type in the name of the station/airport/city/brand and it will drop down a list of their operations. I don't know if it is completely up to date but it is a useful starting point.

Would that be the case if IMC trolleybuses were introduced as they operate some of their route as unwired electric buses?

The building regulations (spit into domestic and commercial) set out the minimum standards that need to be met. TfL and NR are both able to set their own standards for their stations as long as they are not lower than those set out in the building standards. The intensive nature of stations...

"Mr Sands" is a standard theatre term- I think its name comes the use of sand buckets for extinguishing fires.

Motion picture film is the same, 35mm wide but with the length measured in feet (16 frames [images] per foot, camera film was 8 images per foot). To add to the confusion reels of film are sometimes referred to in K referring to kilofeet, for example, 2K is 2,000 feet!

I was giving context (and fully understood InOban's post)- some of the large chains reached Scotland relatively late. Tesco did not have much of a presence until they bought WM Low in the mid 90s. A distribution network is more efficient when the flow is balanced to minimise empty milage. I...

At that time there would be no goods carried to Scotland for Sainsbury's as they did not have any Scottish retail operations until 1984 when the SavaCentre (joint venture with BHS) opened at Cameron Toll which the Edinburgh Sub passes.

Given the long runs between stops, there would be the opportunity for the ticket inspector to carry out other roles such as catering after checking tickets.

The same applies to the London Underground map- it would be a bad idea to use it to navigate when walking.

Pulse Width Modulation (PWM) LED dimming, which is what I was referring to, is used a lot more often than you think- not just in low-cost devices. Having the LEDs either fully on or off, switching between these states many hundreds or thousands of times a second, has the advantage that the...

LED lights are dimmed by pulsing the LED on and off. Reducing the voltage by adding a resister will not provide reliable dimming. It would still be very easy for a modern train to have LED lighting that can be adjusted in colour temperature and brightness. Ideally the colour temperature would...
