A New Signalling System for Automatic Block Signal Between Stations Controlling Through an IP Network
A New Signalling System for Automatic Block Signal between Stations Controlling through an IP Network 1R. Ishima, 1Y. Fukuta, 1M. Matsumoto, 2N. Shimizu, 3H. Soutome, 4M. Mori East Japan Railway Company, Saitama, Japan1; Daido Signal Co.,Ltd., Tokyo, Japan2; Hitachi, Ltd., Hitachinaka, Japan3; Toshiba Corp., Tokyo, Japan4 Abstract This paper describes a new signalling system which controls signalling field devices of automatic block signal between stations through an IP network. The system improves the method of the system already installed to Ichikawaono station on the Musasino line in February 2007. The Logic Controller (LC), placed in a signal house, exchanges the command and feedback data with the Field Controller (FC), placed near each automatic block signal, through the Ethernet Passive Optical Network (E- PON). Following the command data, the FC electrically controls signalling field devices such as signals, track circuits, transponders of the Automatic Train Stop (i.e. Automatic Train Protection) system with Pattern (ATS-P), transponders of the S-type of ATS (ATS-S), and output relays. Only optical fiber cable requires between the LC and the FC. The system has high reliability because the LC, the FC, and the data paths of E-PON are all duplex. The system provides sufficient maintenance information through the IP network. The system can realize higher reliability, less wire-connection- work, less amount of cable, cost cutting, and faster troubleshooting. A prototype system was under evaluation on the Joban Rapid Service line between Mabashi and Kitakashiwa from August 2006 to January 2008. Evaluating the results of the field test, we conclude that the prototype system is technically suitable for signal control. -

IPMS April 2015
PREZNOTES IPMS Seattle Spring Show 2015 Show Calendar Needs YOU! Thanks to Chellie Lynn This Saturday at the Chapter meeting we need to sign up more members to help out 4/11/2015 Lynnwood Galaxy with the Spring Show. With 100 or so paid 4/18/2015 Portland 25th Model Car up members, you would think it would be Fest a cinch to pull off a model show, even one 4/25/2015 Renton IPMS Seattle the size of the IPMS Spring Show. But it 5/3/2015 Puyallup MCS 26 simply isn’t. Our Show is a big deal, and 6/27/2015 Chehalis Billetproof requires a massive amount of bodies to 6/27/2015 Kitsap Fair NOPMS make it work effectively. 7/24-26/2015 Puyallup Good Guys 7/22-25/2015 Columbus OH IPMS By effectively, I mean that in order to get Nationals folks to volunteer, we don’t want to be a burden by requiring them to work so hard, and for so long, that they can’t personally enjoy the show. We need to balance out the effort, so that while people volunteer to work the event, they also can find time to shop with the vendors, and view all the lovely models on display. This means limiting folks to working less than half the show time, so that they can spend the other half, well, NOT working. Otherwise next year, having been overburdened, folks will baulk at the idea of putting on a show. Seattle Chapter News So if you want this Show to continue, if you want to have fun helping people out, while at the same time enjoying a great day at the region’s largest scale model contest and show, please sign up for a task slot or two at one of these areas: Registration or Raffle (both provide a seat In This Issue to sit on), Hosting, or Judging. -

Buildings 91 Introduction: The Nature of the Real Rhett Russo The challenges associated with depicting the real have played an important role in cinema, literature, art, sculpture, and philosophy, but have yet to be fully exploited by architecture. Nonetheless architecture shares many of the same ontological predicaments with these other arts—the introduction of iron, the invention of photography, and the Industrial Revolution are a few examples of crucial developments, which have significantly challenged classicist doctrine. The realist painting of the 1850s, in particular works by Gustave Courbet, confront the viewer with the realities of labor in a new way. With Courbet, reality is presented through the tensed body of the kneeling peasant in Sifting Wheat (1854) or the brokenhearted embodiment of the Wounded Man (1854). Similarly, the emaciated travelers depicted in the Raft of the Medusa (1818–19) emerged from Gericault’s careful practice of painting dead corpses—and seizing the opportunity to speculate on the aesthetics of historical events. These unusual practices formed the core in the developing aesthetic category of the “real.” As Michael Fried has remarked, the content of realist painting presents a particular challenge for historians, due in part to the shift in emphasis toward depicting the “everyday,” but also Rhett Russo Rhett Russo because its resultant strangeness dislodged it from the framework at the moment of its crew’s rescue. -

FOLLOWING RAILWAY SIGNAL INDICATIONS Train Crews Do Not Consistently Recognize and Follow Railway Signals
FOLLOWING RAILWAY SIGNAL INDICATIONS Train crews do not consistently recognize and follow railway signals. This poses a risk of train collisions or derailments, which can have catastrophic consequences. The situation For over a century, Canada has relied on a system of visual signals to control traffic on a significant portion of its rail network. These signals convey direction such as operating speed and the operating limits within which the train is permitted to travel. Train crews are required to identify and communicate the signal indications among themselves, and then take required action in how they operate the train. Sometimes, however, train crews misinterpret or misperceive a signal indication, which results in it not being followed. In the absence of physical fail-safe defences, this could result in a collision or a derailment. How often does this happen? Since 2004, there has been an annual average of 31 reported occurrences in which a train crew did not respond appropriately to a signal indication displayed in the field, and the number of occurrences each year is on the rise. The years 2018 and 2019 have the highest number of occurrences, 40 and 38 respectively (Figure 1). Figure 1.
