Hi. There are various TfL Standards for color, signs etc? , Is there a design or technical standard for the station layout/size (including platform tunnel size etc ? I have two reasons for asking.. 1. I have some concerns that a station I used in the last 6 months might have too few ticket barriers for its load ( but this might be a limitation of an existing site.) 2. I was wanting some geometric data so I could in the future update some objects for OpenBVE accordingly.

Short answer - yes there are loads of standards applicable to TfL modes. have a look here - tfl.gov.uk/info-for/suppliers-and-contractors/design-standardsThe LU Design Idiom is the key one for LU stations plus the signs manual. Both accessible via the above link.

The number of gates is normally governed by a station layout dating back to a time before any such equipment would have been envisaged. They squeeze as many as possible into the site. Modern stations are designed by architects working to a brief but still constrained by the physical layout of the site. Land in London is very expensive. In the past there were things like The UTS (Underground Ticketing System) Handbook which specified minimum measurements.

Thanks, The design idiom document didn't give me the formulae for working out the ticket barrier numbers though, so I'll read it more carefully. I used to do all the gate and ticket machine calculations as well as verify and comment on station layouts. That was a long time ago, though, and I expect the approach has changed because of the removal of ticket offices, shift in ticket type usage and proportions of people actually needing to use ticket machines. In the past there was a cautious approach to ticket gate calculations both in terms of the demand quantum and allowance for growth plus the gate throughput. I've seen quite outrageous (IMO) throughput numbers quoted in TfL press releases. Quite how those numbers are justified I don't know but I assume someone has done some very thorough testing and observations *if* they are used for calculations purposes. I don't think it would be right to share the old formulas simply because so much has materially changed and I've no idea *how* they've changed in terms of official calculations. I'd be interested to see it but I really doubt TfL would be prepared to release the info via a FOI request. Oh and just for the pedantic record they are ticket gates not barriers although no one in officialdom seems to care these days. When gates were first introduced a great deal of care was taken over language because of the ridiculously hostile press [1] the ticket gates got when first installed. Nowadays they're generally accepted as "part of the furniture" so no one pays attention to the language used. A barrier line consists of the vertical poles and glass panels used within an overall gating installation to provide separation of paid and unpaid areas. I think it is just worth adding that it would not be a great surprise to me if we are now finding a number of gatelines on the system that are "under pressure". The Tube has seen very high levels of sustained growth with demand still growing. Even though LU has improved a number of locations on the system to create more space this is expensive work in many cases. "Fixing" gatelines is not a simple thing in many places because you can't just knock down walls because stations are listed or have recognised heritage features. You may also find other issues like encroaching on tenancies or find the floor isn't strong enough or there is a structural beam in the way. Every station is unique. [1] the Evening Standard branded them "mechanical rottweilers" when they went live at Kings Cross Met.

There's certainly some stations where common parlance is still UTS gates...!
