View Full Version : Screaming Trains

11-10-2012, 11:08 AM

Im new to this forum, and railway modelling in general...re-taking up a hobby i enjoyed when i was very young.

I think i have made a basic mistake straight away, in buying some engines off ebay.

One is an Intercity 125. The 2 trains move, but scream and screech their way around the track, as if there is something wrong in the engine.

The Intercity, also moved quite slow, so i have decided to send back, and the seller has kindly agreed to refund.

Is there a simple way of resolving issue like this? Or do i just need to be careful where i buy my engines from?

I would like to repair the other train if possible, as it is a lovely looking train...looks like the Flying Scotsman, but with Cheshire on the side.

I have new track, and new power unit....so want to know if there is anything i can do to save this train?

I hope someone can help me.

Many thanks,
Tom Lawrenson

I assume these have the old Ringfield motor fitted (Pancake looking motor)? If so, the screeching while running is 99% of the time due to the small gear wheel slipping on the motors shaft. If its one of the grey / silver coloured gear cogs it can be carefully replaced with the improved brass cog gear. Sold by specialist Hornby spares dealers. But these are quite difficult to press onto the motors shaft without causing damage to the shaft or motor bearings.
The other alternative is to carefully pull off the grey metal cog and throughly clean the motor shaft and the inside of the gear cog with Meths or Isopropyl Alcohol (IPA) and then apply a tiny drop of Superglue to the top of the shaft. Then push the gear cog back on so as the superglue locks it into its correct position. Ensure no glue gets onto any other of the gear cogs or onto the motors bearings! Do not run the motor for at least a full hour to allow the superglue to cure fully. While waiting, clean the motors commutator segments with a fibre pencil and ensure the two motor brushes are not worn - replace if necessary.

Finally apply special model oil to both motor bearings and to the gears. Use a sewing pin dipped into the oil to transfer the oil to the area needed and ensure only the smallest amount is applied. Remember the rule of lubrication.... If you can see it (the oil) then its probably too much! BIf necessary blot off any excess oil with a small piece of kitchen paper towel.

Note on oiling..... Only use oil sold specifically for model railway use. Most model shops will sell the correct oils. Never use WD40 spray types of lubricant nor 3 in 1 oils which is too thick and only suitable for your bike chain etc!

I'd try oiling the bearings first. Pick a drop up with a straightened out paper clip or other piece of thin, stiffish wire and apply to the shaft, both sides, where it comes out of the motor body.

You all sound as if you know what you are talking about...

...but is there any way of posting pics up here? I could then send a pic of the inside of the trains Tender...as i wont lie, im not very savy on these kinds of things.

I appreciate your help though...and will definately be sticking around on these forums.

There is a guide to posting images in the "Site Help" section.

Hi SWA, If your motor is in the tender it definately is a ringfield. The explanation given by Flashbang regards the noise coming from the motor is very good and the only way to eliminate most of it. I have successfully eliminated a lot of the noise on one of my locos with the same motor just by cleaning the gears, then lightly oiling them. I also have an intercity with a similar motor, but it runs really well and quiet. Welcome to the forum by the way.
