Ballastless railway track has been recently recognized as a feasible solution that increases stability of the railway track and\nalso reduces the cost of maintenance. However, little attention has been paid in past studies to understand how this railway\ntrack responses to moving trains traveling at...
Alas, the prototype had nine. The aisle (south) side of Tony’s superintendent/dispatchers’ office shows one triple window, but there are four more on the track side and left end. He kitbashed the building using three Walthers Merchants Row III kits. Tony Koester photo I acquired an ...
An aerial drone photo taken on July 11, 2024 shows an electrical multiple unit (EMU) train moving at the Dajue Mountain Scenic Area in east China's Jiangxi Province. A batch of 30 electrical multiple unit (EMU) trains, part of what is called the "mountain area elevated monorail sightseeing...

on a new concept: the rail drones of the future. They will be moving on the track ahead of the train, and programmed to run autonomously. Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot. With their abilit...
The track structure is modeled as an Euler–Bernoulli beam resting on embankment. The train is treated as a series of moving axle loads; the embankment and ground are modeled by the 2.5D finite elements. The dynamic responses of the track structure and the ground under constant and vibrating ...
A system for transmitting local information to a moving train in binary code comprising a number of conductor loops arranged one after the other along the track at the local information point and energized from an alternating current source and a loop aerial on the train which becomes inductively...
Photonics Keeps Trains on TrackBrent D. JohnsonTraffic controllers for the national railway system have a problem. They have to move some 550,000 freight and passenger cars along 173,000 miles of track, frequently without knowing the precise location of a train or which way it is headed. The...
