I'm looking for information on the conversions of steam locos from coal or wood to oil fireing. 1. Did they add tanks where the coal or wood had gone? 2. What did the oiling stations look like? 3. Were there any changes to the outward appearance of the locos? 4. Did the 0-4-0 and 0-4-2 Porters use a tender to carry the oil? 5. When were the first locos converted to oil? Any other info on oil fireing would be appreciated.
