APC (Auto Power Control) Magnet Boxes - OO Gauge (Pack of 8) - SET E5-7

This pack includes 8 APC Magnet Boxes (unpainted) - SET E5-7

Overhead Electrified lines are split into electrically separate sections (often up to 30 miles long) separated by Neutral Sections. APC (Auto Power Control) magnets are used to ensure the power draw from a train is switched off when passing through the Neutral Section to prevent overhead line damage.

APC magnets are normally mounted to the sleeper ends on both sides of the running line 30 metres before and 10 metres after a Neutral Section as follows-

Each overhead wire neutral section can be up to 45metres (approx. 2 x Mk3 Coach lengths) long and is split up into the following sections,
• firstly there is a 30 metre run-in, this is from the first set of APC magnets to the insulated part of the Neutral Section, 
• secondly there is a Dead Section (up to 5 metres long), which includes ceramic insulators then a dead section then more ceramic insulators, 
• lastly there is a 10 metre run off, this is from the end of the insulated section to the second set of APC magnets.

An optional extra to go with your APC magnets is our Neutral Section trackside signs which can be found here (Product 4WH0603701).

SET E5-7 - Supplied unpainted; a light coat of primer is recommended before painting / weathering to suit your lineside.  They are often yellow to make them easily distinguishable for track workers.

Note that this product represents the APC magnet boxes, they are not actually magnetic!
