Let's see how you go with this one...
The mileposts on the East Coast Main Line, are numbered in three sections. Where does each section go from and to? And which one is numbered in the opposite direction to the others?

Well, I know from personal observation that once north of the border the miles count down towards Edinburgh, so I'll hazard a guess at the other two sections being London to York and York to the border as I dimly recall something about a famous milepost zero at York.

Sorry for the delay in responding! (Wifi woes!

Absolutely correct
1) London to York, built by the Great Northern;
2) York to Berwick-upon-Tweed, built by the North Eastern;
3) Edinburgh to Berwick, built by the North British, and so numbered in the opposite direction.
So the rails are yours @Peter Mugridge

Thank you - and a fairly easy one from me for a change:
Three* preserved railways label themselves after flowers. Which ones are they?
*If there's more than three then I'll accept the first three given.

I was thinking of the Poppy Line, but I'll give you that as you certainly had two of them, therefore a majority, and the Watercress is certainly a plant if not a flower, so that's 2½ out of 3.

May I ask where the Poppy Line is? It's a new one to me.

North Norfolk Railway.

Ah, I've heard of that line, the one out of Sheringham to Holt; didn't realise they'd named it the "Poppy Line"!

In 1947 the Interstate Commerce Commission in the United States passed an Order which had a profound effect on US railroads. What event led to the passing of this order and what effect did it have?

Did it stop regulating rates for long distance trucking?

No, sorry.

The accident on question which led to the ICC order was the Naperville Crash of 1946, where a CB&Q Flyer, which had stopped for a running geae check, was rammed by another in rear approaching at speed.

Based on that, I'll be greedy and throw two different guesses in to the mix:
- observation cars on the back of a train were banned
- train spacing / pathing requirements were changed, to make sure that passenger trains were kept further away from other trains

Not this
This is closer, not quite on the money but as a hint: think what ensures separation of trains.
No, sorry.

Signalling blocks?

Something to do with what protects signalling blocks.
This Act still affects US railroads today but probably most strongly affected/affects railroads passenger operations.

Presumably train protection - but it couldn't have been full blown ATP because that's what PTC is being rolled out to do today. I recall that there is a US requirement for cab signalling and a form of ATP for passenger trains exceeding a set speed (75 mph?) Does that date back so far?

Interlocking?

I think I was unfortunately too vague there so my apologies, but to do with signalling was what I had meant.
Yes - cab signalling/automatic train stop (not unlike AWS tbh) rather than full postive train control such as ATP.
It does date that far back, though the usual figure is 79mph.
On the 25th April 1946, Chicago, Burlington & Quincy train no. 39, the Exposition Flyer, ran into the back of train no. 11 the Advance Flyer which had made an unscheduled stop at Naperville, Illinois to inspect its running gear. 45 people were killed and 69 injured in this accident, the accident compounded by the trains being formed of a mix of lightweight and heavyweight cars. The accident was caused by the failure of the crew of no. 39 to comply with the signal indications while running at 85mph.
In the wake of the crash, the Interstate Commerce Commission (ICC) opened Docket 29543 on May 20, 1946, with a view toward requiring the installation of cab signals, automatic train stop or automatic train control on all lines where trains operated in excess of 50mph. After hearing opinions from several railroads on the matter the ICC decided upon the following requirements:
- Any of cab signalling, automatic train stop, or an automatic train control to be required wherever passenger trains were operated at speeds of 80mph or greater.
- A form of block signalling system wherever passenger trains operated at a speed of 60mph or greater.
- A form of block signalling system wherever freight trains operated at speeds of 50mph or greater.
The main result of this order was the reduction of passenger train maximum speeds to 79mph outwith cab signal or train stop territory, and to 59mph in so-called 'dark' territory. Similarly, freight train speeds were reduced to 49mph in "dark territory". A few railroads did install cab signals or train stop to preserve higher speed limits, such as the Santa Fe which had the most to lose on its long-distance streamliners by dropping to 79mph, though by this time it was apparent to most railroads that additional investment in passenger traaffic was not really warranted.
In fact, most of the previous installations of some form cab signals or train stop were in response to an earlier 1937 ICC order requiring their installation on at least one subdivision of each road for experimental purposes. The railroads were free to chose which system and route to install it on.
Ironically the Santa Fe which installed train stop on hundreds of miles of route (the greatest installation after the order was passed) in order to maintain 90+ running on its crack services had only until October 1952 to comply while the CB&Q itself put off reducing to 79 outside of its cab signal territory until as late as 1957!

OK. What (of railway interest) happens at Gallitzin?
Had never heard of the place -- just had to Google it, thereby putting self out of running, at this stage anyway.

Bankers added for the Horseshoe?

You are on the right railroad and the right location - but not bankers. Maybe I was a bit misleading in saying "what happens" - it's a piece of infrastructure that I am thinking about.

Time for a heavy clue so that someone else can have a go:
@hexagon789 got the right railroad (built by Pennsylvania RR, now Norfolk Southern) and is very close to the right location. Horseshoe Curve is within 3 miles as the crow flies (5 miles as the railroad winds) of the location I have in mind. Horseshoe Curve is part of the ascent of some mountains (but which ones?), and what might you find near the summit?

Guessing time. I only know two mountain ranges in the US and it’s not the rockys. So.
