Train Progression: Diesel Locomotive

No more shovelling coal into a magic firebox. The Diesel locomotive runs on liquid Diesel, pumped straight into its 1500-unit tank — place a pump at your station, stop the train, and watch the arm connect.

Diesel

Refined in a chemical plant from both middle fractions:

30 light oil + 30 heavy oil → 60 Diesel

A dual oil sink that lands exactly at train timing: the technology needs only railway and oil processing, so diesel arrives the moment your first refinery runs.

The locomotive

• Vanilla-comparable performance (259 km/h, standard acceleration)
• 1500-unit onboard tank — a full tank holds 2.25 GJ, roughly an hour of full-throttle driving
• Refuels via pump at any stop; pump arms visually deploy, clamp, and retract
• Departing waits for the arms to stow — a small ritual this class of vehicle earns
• Built from its working parts: engine units, a storage tank (the fuel tank), a pump (the fuel system), and fuel lines

Roadmap

Phase 1 of a steam → diesel → electric train progression ladder:

• Steam locomotive (next): coal or wood firebox plus water — with water tenders via fluid wagons
• Vanilla replacement (later): optional startup setting replacing the vanilla locomotive
• Electric endgame provided by Realistic Electric Trains Continued 2

Requirements

Requires Fluid Trains Continued (the pumping framework). Base game 2.0 — no other dependencies.
