Hi Lawrie,

Not sure exactly what you mean but
- your pictures show no trouble
- if the motor starts whan you push the axle on the B Side of your picture, it means the collector and brushes need attention.

I suggest in that case to remove the brushes (one is copper one is graphite) they should be approx 5 mm long (if much shorter or very dirty they need replacing)
With tweezers try to clean the inside of brush holders (that folded brass sheet), make sure they are not bent (the brushes can move freely Inside) and that the springs are pushing gently the brushes (If you have another Marklin flat collector motor, compare the pressure)

The next step if still not working is to open the motor but it is delicate, try to avoid it.
I hope this helps

Jean

Thanks for the (quick) input, much appreciated. :-)

It makes sense of my issue.

Any links to a diagram for this model or similar would be good

Sure I can work it out but only after a dram to steady my hands.

Cheers

Here's the exploded diagram from the Marklin website:

I concur that you may need new brushes. Try pushing on them to see if the Railbus starts, that will confirm the issue. The brass coil brush, goes in the brush holder with the 90* angle at the end of the spring.

Hope this helps,

Harold.

Well,
It was the bushes. The left hand one is almost new but the right hand side (brass?) is about 2mm.

Now, to source a pair seems less straight forward. Most ebay sites I can find teetotal cost is over £24...mainly postage from either Germany or the US.

I have found these:

Be great if they did the job :-)

Any ideas?

Thanks

Lawrie
