All, I have been studying old prototype documents for the Victorian Railways, my prototype. Some interesting terminology is:

Hi Mark The Great western Railway used the terms compound and Double Compound. Check and Guard rail are still used and are often interchangeable. I've not heard of Delta or Deltas. Cheers Phil |

Thanks, the colonial government took on a certain I K Brunel as some sort of representative in the old country, maybe he is responsible for the use of compound. I should have added that the VR was an Irish Standard Gauge (5'3") system thus there was little room to spare when putting a diamond between two 11' 8" spaced tracks. Mark |

I've always considered check and guard rails to be 2 different items. Check rails on inside of curves, through switch and crossing work and level crossings. Guard rails on bridges and viaducts, to guard against derailed vehicles going over the side. (Or at least minimalize if vehicles remain upright and at low speed). Kev Staddon |

Mark. OK, although I didn't realise at first it was Australian (VR) Each country etc to their own, am only really familiar with UK practices, 30 + years in the industry although not involved with track for the last 20. |

Hi Mark. The joys of the various colonies, then State Governments in Australia. The style of permanent-way and terminology varied depending on the system most favoured by the commissioner and his immediate underlings appointed to run it. On New South Wales Government Railways it's fun to look at the colour changes on motive power and rolling stock depending on which, (mostly English), railway company was most favoured. NSWGR preferred the term slip as opposed to compound. Compound crossings had an entirely different meaning, referring to the type of curvature leading into the crossing. Kev Staddon's description of Check Vs Guard rails is basically the same for New South Wales. Their definition for plate-layers was; CHECKRAILS (NSWGR house spelling) are rails placed parallel and in close relation to the "running face" of "running rails" to contact with the backs of the wheel flanges and control the position of wheels. GUARD RAILS are rails placed between "running rails" at bridges, openings and through certain over line structures to control the direction of derailed wheels. Mark, the Deltas sound interesting. What does it look like? Is it an attempt to get check rails into the very confined space of the crossing? Kev, Australian railways were mostly built to English practice in the mid 1800's. Most of the locomotives, rolling stock, materials, track design, lead / turnouts, indeed, the whole kit and caboodle including the engineers in charge were imported from the "Mother Country". We didn't have the industrial capabilities for quite a few years, and then we didn't have the capacity for a while after that. Regards, Matt M. |

I do have a model of the rarer reversed version of a delta as per the link. There was one of these in 1964 right on the main Melbourne Adelaide line at Dimboola, photo of prototype is in the Train Hobby books again. Mark Bau's VR web site has the Permanent Way Correspondence Course Book 2 which includes all I know about deltas including drawings. http://www.victorianrailways.net/infastuct/infastructhome.html Mark |

Thanks for the link Mark. Course Book 2 was very informative. So far haven't seen anything like the Delta in the NSWGR permanent-way books up to 1930's. Matt M. |

I am trying upload drawings of NSWGR turnouts but they are PDFs rather than images, is email an option? The other option is to re-scan in different format. Mark |

Hi Mark, Did you check with Greg whether or not he would be happy for you to post copies of his work? He is fairly approachable but is cautious about allowing internet downloadable copies of his work to exist. Regards, Matt M. |

Martin, Greg is happy for his drawing to be used to help with a 1:16 drawing but doesn't want them downloadable by others. Any suggestions? Mark in Melbourne |

Hi Mark, I have found this page, which contains links to a huge number of original railway drawings: http://www.victorianrailways.net/infastuct/infastructhome.html e.g. http://www.victorianrailways.net/infastuct/W&W_standard_plans.pdf http://www.victorianrailways.net/infastuct/aa_fseries/f319.jpg I don't know if that's relevant here. Knowing nothing about Australian railways I'm a bit confused. The title of this topic relates to VR but your previous posts are about NSWGR. I know there is a mix of gauges and a lot of mixed-gauge track. cheers, Martin. |

That's my normal go to site but it only contains 5'3" and 2'6" drawings. We are modelling the first incursion of Stephenson's Gauge into the railways of Victoria so I am going with the assumption that they used the NSW (SG) standards. A Colin Rutledge gave me the following information and he has the respect of others regarding the construction of this railway. I am surprised by how tight they were considering this was all new track in 1960. "The original turnouts were 94 lb rail with 22' 6' blades and a 9.73 vee crossing. This was for both the main line turnouts and the turnouts into the cripple tracks. When the turnouts were renewed in the mid 1980s they became 60 kg 7 metre blades with a 10.0 vee crossing for the main line and the cripple road turnouts remained the same as they were." |

Hi Mark, Are we talking the run up from Albury to Melbourne? While I'm not up with the Commonwealth Railway's per-way standards, by 1960's the Commonwealth would have been using Australian Standards. The NSWGR would also be using the same. The application may be different though. NSWGR is flat bottom, inclined track but not inclined through formations at that time. Plating through formations are specific to time period and use in NSWGR. Not sure about VR. Or Commonwealth. I have to say that 94 lb rail with 22'6" switch and 9.75 crossing doesn't sound standard for NSWGR. 20' switch and 9 or 10½ crossing is more standard. Specials are, of course, done when needed. 30' on a housed switch is also standard. I admit my knowledge of 1960's per-way is weaker as most of my research is pre 1935. You would need to find out who was the responsible body for the work (probably an Australian or State Government department) and see if there are any records left that specify the standards. Regards, Matt M. |
