Overhead Layout

This O-Scale layout was designed and built for a customer in Chicago. The customer had an existing two track oval layout over the pool table and we did a little customizing. We added a two track staging yard along the wall to store trains. We added a long extension of track down a hallway and into another room. The layout is controlled with MTH DCS and Lionel Legacy command control. The switches are controlled by the DCS handheld through an MTH AIU. All of the buildings are lit and there are various Miller Engineering signs along the route. The customer wants us to add more custom buildings soon. Enjoy!

New gantry for overhead wires that power the electric trains. Taken through the window of a moving train, just out of Wellington station.

Extensive work is underway on the Wellington regional railway in preparation for the arrival of new electric trains in 2010. Many new substations are being built. The overhead cables and tracks are being upgraded.

How is electric power transmitted to trains with the overhead cable?

Question by Snow C: How is electric power transmitted to trains with the overhead cable?
Since the overhead cable is only one contact, and any circuit needs to be closed, where does the current flow out of?

Best answer:

Answer by Marc Robertson
The circuit has the live power on the overhead cantilevers and is grounded by the rails which complete the circuit. This way there is no live power and ground right next to each other that humans or animals can be killed by.

Ironically, every locomotive is electrically powered. Most locomotives are diesel electric because a traditional transmission won’t work. Basically the power is fed from a huge diesel motor into a huge generator. The power goes through a drive which controls the power. Then it goes to multiple traction motors simular to electric trains.

Correction: Every diesel locomotive is electrically powered, China still runs steam powered locomotives…
