It's Steamy Sunday here on the Blog! Today's image is one I took of the Porter locomotive as it sat by the Roundhouse right before our safety meeting. The Porter is a tank engine and carries it's water supply in a tank over the boiler. This can help provide traction but can also cause issue as water does not want to inject into a boiler when it is too warm. Since the water is sitting over a hot boiler the water supply needs to be kept fairly full to keep the water cool enough to inject efficiently.
Every arrangement has its pros and cons I guess
ReplyDeleteYes, most likely.
