This is all from the point of view of regular 1822, which we haven't
played in a while, oops.

The map is stupidly big, like Canada. There are a lot of separate
station cities.

Ten dit hexes are grain elevators (eg Moosejaw (J16)). Four coastal
cities are ports (eg Prince Rupert (A7)). An ordinary train scores $10
extra from a grain elevator and $10 extra from a port if there was an
elevator on its route.

Pullmen earn no extra revenue from grain elevators or ports. They
treat them as normal dits and cities. A Pullman on an N-train can run
to N cities and 2N dits (I think in regular '22 it's unlimited dits?).

"Grain trains" are like Pullmen in that they attach to existing
trains, they're not trains in their own right. A grain train doesn't
count grain elevators towards its total stops, but scores $10 for each
grain elevator it runs through (note that it does _not_ score the
normal value of the dit) and $20 for a port if it visited at least one
elevator. 

Like the LNWR in '22, the CPR has ten 10% certificates and starts with
two tokens on the map.

For track laying and token placement, you can trace a route through
multiple stations on the same tile, but not for actually running a
train.

There's double track into Buffalo (AC23) and Detroit (Y29), a bit like
the English Channel in '22. You can't use this to run two trains until
the green tiles - those have double track printed for the connecting
hexes.

There's a minor (M13) like the one in London in 1822 which picks one
token spot in Toronto (AC21) which it shares (it doesn't stop another
company putting a token there). It pays $20 to place its token which
counts as its first track operation. Rule 7.1.2 says you can acquire
M13 if you have a token in the shared station; I don't think this
stops you tracing a route to it in the normal way, it's just meant to
cover the rules question where you have an isolated token sharing with
M13's token and does it count as a route if it's got no track in it?

There's also a private (P10) which gives a similar conjoined token in
Winnipeg (N16). P10's ability is a teleport, you don't need to be able
to trace a route there to acquire it.

Majors GNW and NTR have destination tokens in specific slots in
Winnipeg, and must route to those slots to place the token.  Major ICR
can route to any slot in Quebec (AH8), but then must place its token
in the slot it routed to... even if the slot is full, creating a slot
with two tokens in like the above cases.

You move left _n_ spaces if the Director sells _n_ shares; one left if
another player sells, no matter how many were sold.

When you acquire a minor you can immediately lay or upgrade one
tile. You can't upgrade a tile you placed or upgraded earlier in the
OR, or use a private with track abilities during this build.

If the bank breaks during an operating round, finish the set of ORs
and play one extra OR.
