Is it getting any shorter?

a mum with antlers? I think not

That map is from about 1850. Major rebuild around 1903 and many later changes. Suggest searching nls for a large scale map of the era you wish to model.

That plan is not entirely faithfull to reality. There was (and stiil is) a trailing crossover to allow departures from platform 6 to the Up Main. There never was AFAIK a facing crossover Down Main/Up main just east of the platforms. Fisherton Yard never had a direct connection to/from the running lines - it was connected to the stub end of the GWR Down line which was a kickback from platform 1; just as the present day Traction Depot is connected. Several other changes possible depending on your space/desires.

It ran out of beer?

IIRC When 442s were diesel hauled on engineering works diversions, it was quickly discovered there was no interlock to the doors.

Probably Feb 7th, as that is the first Wednesday of the month.

according to RTT trains running again commencing with 1821 EXC to BNP

There was previous legislation which I believe was superceded by the 2011 act. IIRC legislation was introduced soon after WW2. As well as various safeguards to protect young fingers etc it also limited the maximum voltage for powered toys to 24v. Previously , I think, there had been 110v locos!

It is a legal requirement. Toys intended for under 14s must meet the Toy Safety Regulations 2011

Would it need to be a loco? A generator van could fulfil the same purpose.

for the ULEZ?

Perhaps robots have worked out how to get around the "I am not a robot".

Do any other retailers sell these carriages?

Is it the .......ah! goon show?
