Re: What to do for a "Run away" loco

Hi All
The same exact problem did occur with Southern # 4501,, many years ago,, the drypipe, let go,,because it was worn thin, by Steam..
At that time the locomotive was on one of its excursions,, when it happened,, Walter Dove was the engineer, when it happened,, the only thing you can do, according to the story, that was in Trains magazine,, or the story of 4501 was to turn on everything and reduce the boiler pressure.. and throw the Johnson Bar,, in neutral.. and apply the brakes..
Once the boiler pressure was reduced,and safe to move, the locomotive was put onto a siding,, and the excursion continued with diesel power. the locomotive was brought to the shops for dry pipe repair..
The new dry pipe was cut into sections, and put through the steam dome, and welded in place,,the locomotive was tested, making sure the new dry pipe was in working order...
The following week, the locomotive was back pulling excursions,, as if nothing happened..

The normal procedure would have been pull all the boiler tubes out,and then replace the dry pipe,, as one big section,, Pat.
