Is platform 3 at Mudchute an acceptable answer, or is the DLR system out of scope?
Seems very acceptable to me. Though Mudchute is an interesting one, as it started as the original route to Island Gardens, then became a siding, and finally a bay. Doesn’t seem to be used very often - it seems to be more of a refuge siding which happens to have been made to double up as a platform, but being a platform now I’d say certainly qualifies for this thread.
I would agree with this. A station at which all trains terminate, and which is also not on a through line (like Terminal 5), does not mean it can have a bay platform.
I would however wonder if an argument could be made where the platforms are staggered, such as Ealing Bdy (District) which has the buffers for one platform noticeably further back than the buffers for the other two.
Yes don’t entirely see why not, especially if a location was designed as a potential through station (can’t remember if that applies in the example given).
Edgware platform 1 could qualify under the same criterion, especially as it came later than the other two platforms. However Edgware is complicated as today’s layout isn’t what was intended had Bushey Heath happened.
