Why does Lionel track have 3 rails?

Lionel used the center rail for power and the two outer rails for ground. This made complex track setups very simple using the technology of the day. For example, with a three-rail system, the track can loop back on itself without any issues.

What is bigger 2 0 or 2 AWG?

2 AWG will handle around 94 Amps, while 2/0 AWG will handle around 190 Amps. The length of the wire must be considered as well as the % voltage drop in order for this to be true. For a 3% drop where the load is less than 20 feet from the battery and you are drawing 100 Amps, you would need 2/0.

### How can I run two trains in one layout?

with block control you can have two trains on the same track travelling in opposite directions, as long as they are in seperate blocks connected to diffferent power packs. two locomotives in the same block will be controlled by the same pack, and thus run in the same direction.

Is O gauge bigger than OO gauge?

The common model railway scales being: O scale – 1:48 Needs lots of space and great for kids as the parts are big enough for children to handle easily. Works with 32mm gauge. OO scale – 1:76 By far the most popular in the UK and uses 16.5mm gauge.

What are the wire gauge gauge standards for model train layouts?

Wire Gauge Standards for Model Train Layouts 1 Track Bus and Feeders. As your layout grows beyond the basic oval of track that comes with most starter sets, a good power distribution network is essential to getting consistent 2 Lighting and Accessories. 3 Switch Machines and Motors. 4 Control Panels and Electronic Projects.

## How do I choose the right wire for my wiring layout?

In general, the larger the layout, the heavier the wire you’ll be using for good performance. Also, the gauge of the wire will be dependent on the type of wiring you’re doing. If you’re doing bus wiring, you’ll want heavier wire for the main bus. If you’re doing star wiring, lighter wire going out from the common connection point will be fine.

What gauge wire should I use for bus wiring?

Also, the gauge of the wire will be dependent on the type of wiring you’re doing. If you’re doing bus wiring, you’ll want heavier wire for the main bus. If you’re doing star wiring, lighter wire going out from the common connection point will be fine.

What are wire gauges and how do they work?

Wire gauges are coded by their size. The smaller the number, the larger the wire. The wire can also be purchased as solid or stranded. A solid and stranded wire of the same gauge will be the same total diameter.
