[Rails-devel] Emergency trains

[Erik V. <eri...@xs...>]

I have uploaded the code and configuration changes for all games currently
in Rails.

Three configuration options have been added in a new <EmergencyTrainBuying>
tag under <OperatingRound>, all having valid values "yes" and "no", one of
these being the default value.
All cases listed below apply to train purchases needing additional president
cash only.  (Purchases with only company cash are always allowed according
to the standard train buying rules.)

1. mustBuyCheapestTrain [from the Bank, with president cash]:
Yes (default): 1830/Kaas, 1856/70, 18AL/GA/TN, 1826, 1851, 1889
No: 1835, 18EU/VA/Scan
[N/A: 1825, 1880]

2. mayAlwaysBuyNewTrain [if not enough cash for a new train but enough for a
used train]:
Yes: 1835 [Disputed; disapproving players are advised to ignore the new
train offer]
No [or N/A] (default): all other games

3. mayBuyFromCompany [up to list price]:
Yes (default): 1830/Kaas, 1835, 18EU/VA/Scan, 1826, 1851
No: 1856/70, 18AL/GA/TN, 1880, 1889
[N/A: 1825]

I will also add this info to the Wiki.

Erik.
