The Electric Pullman
Entering an already crowded and established industry, the Niles Car & Manufacturing Company in Ohio began business with surprising success, producing well over 1,000 electric and steam railway cars-cars so durable they rarely needed to be replaced. That durability essentially put the company out of business, and it vanished from the scene as quickly as it had appeared, leaving little behind except its sturdy railway cars. The story of this highly regarded company spans just 16 years, from Niles's incorporation in 1901 to the abandonment of railway car production and sale of the property to a firm that would briefly build engine parts during World War I. Including unpublished photographs and rosters of railway cars produced by the company and still in existence in railroad museums, The Electric Pullman will appeal to railroad enthusiasts everywhere.

Dynamic analysis of high-speed trains on flexible beam systems with discretely supported continuous rail tracks
The railway track subsystem, vital for directing trains and transferring loads to the ballast and bridge, is crucial for maintaining travel safety and passenger comfort. This work examines the displacement, acceleration, and power spectral density (PSD) values of generalized coordinates established on the physical models of train and bridge dynamics, employing train–bridge interaction (TBI) and train–track–bridge interaction (TTBI) models. This research introduces a novel approach by modeling several wagons, each with ten degrees of freedom (10-DOF). The literature has not thoroughly explored this topic, especially with series bridge systems. The railway track on the bridge girder is modeled as an indefinitely long beam utilizing a multi-layer ballasted track framework, with rail–sleeper couplings sustained by discrete springs, dampers, and masses. The bridge girder is modeled using Euler–Bernoulli theory under-supported boundary conditions, with many girders configured in series to assess their impact on train dynamics. The railway vehicle is depicted as a multi-degree-of-freedom system consisting of a motor car and carriages. TTBI analysis demonstrated a more expedited attenuation of vibrations at the bridge midspan than TBI analysis. The vertical accelerations of the motor car and wagon bodies were determined to be 2–5.26% elevated with the railway track on the bridge, whereas the RMS values of the power spectral density for these accelerations were 95–130% higher in TTBI analysis compared to TBI analysis. This thorough modeling methodology facilitates a more accurate assessment of train dynamics and passenger comfort in train–track–bridge interaction contexts.

The Lego trains book
\"Whether you're a diehard LEGO trains fan or you've been a model railroader since the days of Lionel Trains, you're going to love this complete, illustrated guide to the world of LEGO train building. Sure, the LEGO company has an official line of train models, but official sets can be somewhat limiting -- and expensive. Why not build your own, custom creations without the confines of official LEGO sets? You'll begin with a walkthrough of the official LEGO train systems to get the lay of the land and a feel for its characteristic details and styles. Next, you'll learn how to integrate the style of different sets in your own models, and how to combine standard LEGO building styles with advanced aesthetic techniques (like SNOT -- studs not on top) to create more realistic models. Author Holger Matthes, a star in the LEGO train community, discusses the model-making process, including how to choose scale, wheels, and motors and how to build flexible track, track layout, and essentials like doors, windows, and track intersections.\"--Goodreads.com.

Control of Dust Emissions in Rotary Dumpers for Railroad Cars
The creation of effective aspiration systems for use in tipping systems for railroad cars (rotary car dumpers) is considered. An aspiration system with air-jet barriers is introduced. Dust emissions are localized with at least 90% efficiency. In cyclones, the level of processing is 92.4%.

Sleep train
\"A little boy climbs into bed with a book and starts counting the train cars in it, between the engine and caboose. 'Ten sleepy cars going clickety-clack,' reads the refrain. But as the boy counts cars and gets sleepier and sleepier, his room looks more and more like one of the train cars from his book--the sleeping car, of course!\"--Amazon.com.

Key Technologies of Physical and Virtual Test Rig for Railway Freight Car body
On the one hand, considering that the traditional fatigue method of railway freight cars is based on damage as a parameter, the influence of stress waveform cannot be considered. On the other hand, physical experiments have the characteristics of lag, long period, and high cost. The full-scale physical test and virtual test of car body are carried out. First of all, the data processing method of small deletion and the inverse problem load acquisition method based on data to data are proposed. Secondly, the dynamic stress calculation method with the bench as the boundary is proposed. Finally, taking the obtained load as the input of the physical and virtual bench, a new fatigue test method for simulating the running attitude of the car body line is completed. The acceleration RMS error of the C70E gondola body is less than 6%, the stress RMS is less than 13%, and the equivalent mileage is 3.125 million highway test results show that the car meets the life requirements of the car body. The inverse problem analysis results of virtual and physical tests are basically consistent, and the study of this method provides a basis for improving the fatigue reliability of freight car bodies.

Development of Condition Monitoring System for Electric Resistance Spot Welding Used to Manufacture Railway Car Bodies
Stainless steel railway car bodies are assembled by joining the outer plates and the pillar materials using resistance spot welding. In recent years, more and more car bodies are being assembled using laser welding in addition to the resistance spot welding. For this laser welding system, we developed a condition monitoring system considering the processes before and after laser welding as a single system, and obtained and put into practical use an appropriate condition that suppresses spatter generation during laser welding. On the other hand, in resistance spot welding, the current, weld time, electrode load, and electrode tip shape are the main factors that determine the welding quality. Therefore, the configuration of the equipment is less complicated than that of laser welding system, and the condition monitoring is easier than that of the laser welding. In this study, by transferring the concept of the condition monitoring system developed for laser welding to resistance spot welding, we achieved a reduction of more than 60% in terms of electricity consumption and improved the appearance of the car body by optimizing the indentation shape. In addition to this technical achievement, we also present in this paper a case study showing the opportunity for innovation by restructuring the technological paradigm of the resistance spot welding in the production of stainless steel car body shells.

Application of Cold Plasma to Reduce the Roughness of the Working Surface of a Railway Car Center Plate
This paper presents a study on the use of cold plasma to reduce the roughness of the working surface of center plates of railway cars. The use of cold plasma is a promising method of surface treatment which allows for a significant reduction in roughness without changing the mechanical and chemical properties of the material. As part of the study, experiments were conducted on the treatment of center plates with cold plasma, the surface roughness was measured before and after the treatment, and the microhardness, microstructure, and chemical composition of the material were analyzed. The results of our experimental studies show that the use of cold plasma can reduce roughness by 1.4–1.6 times. At the same time, the roughness parameters Ra are reduced by 29.1–37.4%, and Rz by 29.3–39.6%. A slight increase of 2.81–3.31% in the roughness parameter Sa is also obtained after cold plasma treatment compared to the base samples. Thus, the use of cold plasma for the treatment of center plates of railway cars can significantly increase their durability and reduce the costs of manufacture or repair, making this method promising for use in the railway industry.
