Hello.

I need an instruction leaflet/diagram on how to set up the old control system using the direction changer switch 494N ?

Can anyone help or provide wiring diagram ?

Neil.

Hello Markus.

Thank you for the diagram , yes i will probably have to change the internal rectifier to new components.

I guess new modern rectifiers are quite cheap to buy from electronics shop.

Regards Neil.

Hello Ray.

Yes these 494N units were used to change the direction of the train , it basically generates a large pulse of electricity up to 20-volts which activates the internal reverse units fitted in Marklin locomotives.

As Markus mentioned the rectifier is probably no good now so can be replaced with a modern issue type fitted inside the old casing.

The later blue type controllers had the pulse switch built into them.

Marklin also used larger versions of the 494N for their 0-gauge locomotives in the 1930's.

Hallo Markus.

Thank you so much for pointing this out , i always thought that the 494N was used on early AC locomotives to change direction but now i know this is not the case , sorry Ray for the error in my information about 494N.

As Markus points out it was used for the 700 series with DC current.

So all the 700 series were DC current ?

Which controllers were first used in 1938 for the locomotives fitted with the pulse reverse unit inside ?

Many regards Neil.
