It’s odd how we sometimes use the name of a unit instead of the dimension it measures. It’s pretty inconsistent; you wouldn’t ask someone their ‘footage’ if you wanted to know how tall they were, but you would probably refer to the ‘acreage’ of a farm rather than its area. These quirks aren’t limited to US Customary units either; you’ll hear people refer to current as ‘amperage’ for example.
A more striking case is voltage - which has largely displaced EMF and PD except where the slightly different definitions matter. Simmons, in his 1912 book "Electrical Engineering", doesn't start with a section on units, so it's hard to spot where he introduces them. But he still uses EMF and PD when talking theory, and a few cases of the older pressure, but voltage especially for voltage drop. However, so much of the machinery he is talking about operates at a nominally fixed supply voltage that most of the time he just uses 400 V, and doesn't need to say the voltage is 400 V (which is awkardly repetitious anyway). This usage as a rating is where the -age forms are commonest, I think. So the voltage and amperage of a machine are on its rating plate, but the current varies with the load so needs a separate term. I imagine the acreage, yardage, square footage, tonnage, and similar are also used for rating or ranking. And chainage, of course, on railways. Electromotive Force (EMF) (and its sibling Back EMF), and Potential Difference (PD) and different entities all are electrical pressure the SI unit for the is Voltage. The Amperage stated on electrical apparatus is usually stated as the max rated current, the current draw measured in Amperes (Coulombs per second), and is dependant on the Voltage supplied to the apparatus, load on the apparatus and temperature. Frequency is one of those things used to be stated as cycles per second but to day is Hertz (Hz) I do find it amusing how the USA still use BTU for their heating and cooling and use Inches, pints, quarts in every day life. I think the USA today is where the UK▸ was 50 to 40 years ago in the transition to metric and SI units, USA industry is certainly moving quite quickly to metric and SI units due to international market demands

Anyone care to provide a UK▸ equivalent? We have 100%, Railcard and Groupsave (66%), Children (50%), Priv (well hidden that)! and babe (100%) - have I missed any?
HM Forces Railcard Serving Police Officers and PCSO's have travel concessions, both on and off duty depending on where they are in the country, they must be available (and capable) of providing assistance to rail staff Rail staff "priv" is an open secret ................ just Google "Rail Staff travel card"

According to the GWR▸ website: "The emergency services had reported a member of public on the wrong side of a bridge in the Ealing Broadway area."
I would love to know how you get on the wrong side of a bridge. Tell it "your mother was a hamster and your father smelt of elderberries"?
Allegedly one person in custardy. I was a Paddington caught up in the melee, it seem to take an inordinate amount of time to recharge the OLE▸ . The only think I can think of was a local isolation and Earthing had been put in place to make it safe for the Blue Light services which had to then be lifted

Yes, GWR▸ drivers used to get an enhancement of 0.25 for bank holidays but that was removed several years ago as part of a pay deal. So, Good Friday and Easter Monday are flat rate pay and Easter Sunday is just a ‘normal’ Sunday with a 0.25 enhancement.
Avanti are the same, but I guess some other TOC▸ ’s may still have some form of an enhancement, but even then I doubt it’s a particularly lucrative one.
I take it that they at least get a day off in lieu for working a Bank Holiday? A railway contract I was under a few years ago, and I know is still in use, I got 6 days holiday to compensate for bank holidays being rostered as normal work days the only ones treated as bank holidays are Christmas Day, Boxing Day and New Years Day. Saturdays and Sundays also rostered the only enhanced overtime payments was for working a rest day 0.25. Railways staff are restricted in we must have 12 hours rest between shifts, and can only work 13 days out of 14 ie every 13 days we must have a day off.

What a pity Acton Bank was not electrified or they could run Heathrow Express into Euston.
This has been talked about right from day one of the HEX scheme in the 1990's. There are a number of challenges, the track layout where the UP & DN Poplars join the GWML▸ is setup for freight moves in and out of Acton Yard, Acton Yard will also need to be wired, whilst all this is achievable the crux comes down to who funds the electrification and future Maintainenance. The Freight Operators ( FOC▸ 's) currently due to their tight operating margins they have little or no need / desire to fund the electrification of Acton Yard and Poplars , they are private companies without public funding (unlike passenger TOCs▸ ) The Passenger TOCs have virtually no need for the Poplars to be electrified, the usage into Euston would be limited; indeed running a few trains via the poplars could impact the turning around of services at Ealing Broadway. Network Rail cannot undertake the task alone as it could not justify the funding because neither FOCs or TOCs have a requirement for it. Should Acton Yard and the Poplars be electrified ........... yes ............. but unfortunately there just is not the demand to spend the money to do it

I can understand why they would chose to go cashless.
Cash costs money to process (eg taking it to the bank) There are expensive security measures needed Its open to fraud.
However I suspect the main reason is the number of customers that have been pay cashless out way the number paying by cash
