| − | This page outlines some basic cost calculations I use in my vehicle sets, both pre-calculated spreadsheet numbers, and the code used for variable running costs in the game.  When designing a set in a spreadsheet, it's probably best to use standard numbers first, then fudge values for vehicles which you think need to be more or less expensive.
  |   | 
|   |  |   |  | 
| − | ==Base Costs==
  |   | 
| − | I use the following base costs:
  |   | 
| − | *0F/4B8E for locomotive purchase, multiplier 08
  |   | 
| − | *10/4B94 for wagon purchase, multiplier 0A
  |   | 
| − | *2A/4C30 for locomotive running, multiplier 0B
  |   | 
| − | *2B/4C36 for wagon running, multiplier 05
  |   | 
| − | 
  |   | 
| − | *2D/xxxx for aircraft running, multiplier 0C
  |   | 
| − | 
  |   | 
| − | The NFO looks like this:
  |   | 
| − | <pre>
  |   | 
| − |    1 * 7	 00 08 01 01 0F 08 08 // loco cost
  |   | 
| − |    1 * 7	 00 08 01 01 10 08 0A // wagons cost
  |   | 
| − |    1 * 7	 00 08 01 01 2A 08 0B // running cost
  |   | 
| − |    1 * 7	 00 08 01 01 2B 08 05 // wagon running cost

  |   | 
| − | '''Weight in Tons * ProdCost'''
  |   | 
| − | *''ProdCost'' is usually 0.25, but can be fudged between 0.2 and 0.3.
  |   | 
| − | 
  |   | 
| − | *Example:  [[4-6-0 Jubilee]], 126 * 0.25 = 32
  |   | 
| − | 
  |   | 
| − | ====Diesel and Electric Locomotives====
  |   | 
| − | '''Weight in Tons * ProdCost * (Horsepower / BaseHP )'''
  |   | 
| − | *''ProdCost'' starts at 0.4 for early experimental diesels, 0.3 for 1960s production units, down to 0.22 for 21st century designs.  Again, these numbers are fudgable if you think a particular vehicle should be more or less expensive.  For electric locomotives, early vehicles are 0.5, and is down to 0.4 by the end of the century.
  |   | 
| − | *''BaseHP'' is a "typical" power output for engines of that type/era.  For diesels, I use 2000 for models designed before 1975, 2500 from 1975 to 1990, and 3000 after 1990.  For large electrics, I use 4000.
  |   | 
| − | 
  |   | 
| − | *Example:  [[EE Type 3]], 107 * 0.3 * (1750 / 2000) = 28
  |   | 
| − | 
  |   | 
| − | ===Running Cost===
  |   | 
| − | '''(Horsepower * EffCost) / (SuspCost - MaxSpeed)'''
  |   | 
| − | *''EffCost'' is the efficency of the design, where a higher number is worse; 5 for pre-WWI steam locomotives, down to 4.5 for the latest post-WWII designs.  4 for early diesels, with 3.75 for production diesels from the 1960s down to 3.5 for modern designs.  3 for most electrics.  Very powerful locomotives may need lower numbers and very underpowered vehicles (eg railbusses) may need higher numbers.
  |   | 
| − | *''SuspCost'' represents the wear and tear on the traction system and track, and is a number roughly imagined as the speed at which the vehicle will fall apart.  I use 200 for steam locomotives and 300 for modern electric locomotives, 225 for first generation diesels and 250 for modern diesels.
  |   |

| − | *Example:  [[4-6-0 Jubilee]], (1550 * 4.75) / (200 - 90) = 67
