This is from soot buildup on the isolators. Sweden has one of the longest semi-abandoned but still in service tracks on Inlandsbanan, where steam enthusiasts run special trains during the summer. 1600 km long, max speed 30 km/h in sections. 30 kmh? Is that a typo? I can bike faster. This signature is now the ultimate power in the universe |

This is from soot buildup on the isolators. Steam propulsion isn't banned on all electrified rain lines in Scandinavia. Occasionally there are still steam engines carrying vintage trains from Stockholm C to places like Nynäshamn, Södertälje, or all around Lake Mälaren, on electrified rail lines. A few such tour are expected within the next month. |

Not everywhere but in sections. 70 km/h is a more common speed though on Inlandsbanan, and the most common passenger trains there are diesel motorcoaches. Perhaps the 30 km/h apply to the steam engines only due to their greater weight? |

Is that a typo? I can bike faster. They only keep this railroad operational to service the fiber and high voltage lines running alongside. The minmum service level equals a max speed of 30 km/h. Which is fine if you use it 5 times a year to bring in equipment to some other bits of infrastructure. It is only around 5% of the line that is that decrepit. So there is a lot of track time for museum trains. -- mrr |
