Can you provide a brief synopsis of the specific water treatment regimen and startup/cooldown procedures you are using? These look to be candidates for Becky's 'best practices' manual... |

Were the NJT units made into "F40FH"s as well? Also are you useing the HEP from the NJT units. For those not familiar Amtrak f40ph Randy ATP off the prime mover requiring it to always be revving at Max Speed. A lot of the NJT units installed the separate caterpillar powered head and power generator by extending the rear of the locomotive body over the back porch so the prime mover but only need to move as fast as a corresponding throttle position. |

hadder - Very nice picture and comments report. Glad to see the work being done on #29. My only Grand Canyon run was behind that 2-8-0 unassisted (no diesel helper) so have a warm spot in my heart for her. Les |

Thanks for the updates and pictures. Does the former LS&I #29 get out very often? Again thank you. Regards, John. |

These look to be candidates for Becky's 'best practices' manual... We use a chemical system that starts with DEHA for an oxygen scavenger. Our source water varies. When available, we use collected precipitation. If not available, the city municipal water system gets it's water from either surface lakes or wells, and the water quality can vary greatly. All water sources are run through a sand filter and ion exchange water softener. Chemical analysis on the boiler and tender are conducted after each run, and dosages varied based upon the results. Typically, the Monday before a Saturday operation, we hook the boiler up to a 480V circulation pump and pre-heater. It takes water from the blowdown and returns it through the boiler check. It will raise the temperature about 2-4 degrees an hour, and is thermostatically controlled. By Thursday morning, the water temperature is around 190 degrees. The fire is lit, and we have water boiling in about 30 minutes. The pressure is brought up slowly, around 1 lb. per minute, until full operating pressure is reached. The boiler is secured for the night until 4:00am Saturday morning, when it has about 25 psi left. It's fired up again and ready by 8:00 am. After the run, the boiler is again secured. Monday, when the boiler is cooled down to about 10 psi or less, we hook up the nitrogen to fill the vacuum space after the steam has condensed. We fill enough nitrogen to have the pressure gauge rise about 5 psi. Once a week, we replenish the nitrogen to reach a gauge pressure of about 10 psi, until the next operating day. |

Our NJT units have the separate Caterpillar diesel in the rear for HEP. These are functional and used regularly, although they are quite loud. It seems that there was not much effort put into noise reduction. One of our upcoming projects is to add sound insulation to the interior walls of the HEP compartment. Eric |

What is the status of the FPA4's? What about CB&Q 4960? |

Thanks Eric for a very interesting report. Sure nice to see steam still having a place in that operation. I had the pleasure of being a guest engineer a few years back running the 4960 and it was a real pleasure seeing what a professional operation it is. Best wishes for a great 2018 season.

Eric, Now that you are dumping ballast, does GCR have their own tie and surfacing equipment or do you sub that out? Rob Gardner |

Eric Thanks for the update. I see there are now eight active ballast cars now instead of five. Also are the fire packs different from the ones that Sam Imbleau used to use? Robby |

Eric, The new power looks great. I'm going to be visiting Flagstaff sometime in the fall for a wedding so I'll be sure to swing by for a visit. Would love to see everything that's changed since I moved out in '14. |

Of the 5 FPA-4's that were in serviceable condition, 3 are in long term storage. 6773 & 6871 are in Williams, and 6776 is on display at Grand Canyon. #6793 & #6860 are in operation, and are typically used as trailing units behind the F-40's. Occasionally, we have need for 6 operable locomotives on a given day, and 5 F-40's is not enough. 4960 is in operable service, and has made 3 runs to the Canyon in 2018. It's next scheduled outing is this Saturday, April 21st, in celebration of Earth Day. Quote: Now that you are dumping ballast, does GCR have their own tie and surfacing equipment or do you sub that out?] We have a ballast regulator and small tamper, which we use for small jobs. We contract out each summer for larger surfacing and alignment jobs. The goal is to have the ballast dumped (and ties changed) before they arrive. Quote: Also are the fire packs different from the ones that Sam Imbleau used to use? Robbie, these fire packs were purchased around 2009. Eric |
