Changes, as filed:

• Too essential to fail: the first woodcutters hut, sawmill, fishing wharf, hunters lodge, clay pit, brick kiln, smokehouse and salt works no longer close. The bank lends instead, and the debt blocks their growth until it is repaid. A crier card explains it the first time.
• A train backing out of a jam keeps its wagons on the rails, and returns to driving forward the moment a clear route opens instead of reversing the whole leg.
• Esc closes whatever dialog is on top, the same as its Cancel button, one layer per press.
• Warning text on the green plates reads in a warmer, brighter tone; the vermillion-on-green is retired.
• Loading a save no longer replays the previous world's steamship, which could sail straight into the moored freighter.
• Twenty locomotive tiers joined the catalog, from the shunter to the atompunk imperator. They wait in the sandbox until the campaign learns how to unlock them.
• The vehicle sounds are mod data now, with explicit links, so a mod may replace the whistle without touching the code.
• This is the first release on the default branch of both apps; beta testers get the same build.

The bank trusts these prove satisfactory.
