Hornby 6 wheel coaches derailing?

[Newbie2020]

Hi - Advice required!

 

I have 2 Hornby 6 wheel coaches which look really great behind my Bachmann C Class loco. The problem is the coaches keep derailing on the bends. I have 2nd and 3rd radius curves. Is there any adjustment I can make to sort this?

Have you checked the wheels to ensure they are correctly gauged?

Showing my "Newbieness", how do I do that?

You need to buy a 'back to back' gauge and push it between the backs of the wheels.  If it is a tight fit, they are correctly gauged.  Or you could use a caliper gauge to measure the distance between the backs of the wheel treads.  It should measure 14.5mm in OO Gauge.

Cheers Terry, I have callipers and they are between 14 and 14.5 mm

IMO B2B should be 14.5mm +/- 0.1mm.  0.5 mm is too much.

 

How about a pic of the underframe?

Perhaps check for buffer lock between the tender and the coach.

Thanks everyone, sorry for late reply but had a busy weekend!

 

Some Gaugemaster oil on the centre wheel axle seems to have done the trick.  B2B Gauge on order!

 

Cheers
