Old Triang Trains Vibrate on brand new Hornby Track

[AlloAllo]

Will keep the capacitor as it was there for a purpose, still appreciated it appears!

There are many things at play here.  A member has mentioned a loco slowing down over Hornby Points, the modern R.8000 series points have shallower flangeways which the older Tri-ang loco's don't like.  Your loco's are deep flange period loco's so will need new wheels or the flanges turning down on a lathe to run on modern Hornby track or the use of a rasp and turned down whilst the loco spins it's wheels (this is not for the faint hearted).

For the dock shunter or other Tri-ang loco's other factors are a failed armature coil which may cause stalling or unable to start, weak magnet, poor wiring causing a short usually due to vibration and a wire not insulated properly, also soldering directly to brushes isn't a good idea either as this causes issues when you want to change them and can put extra pressure on the brushes causing premature wear.

The capacitor for RF suppression is still a legal requirement as it can interfere with computer systems, ham radio, some lab equipment and old analogue radio systems as well, failure to have a working one fitted could be a legal issue if found to be causing RF interference.  Ofcom deal with RF issues and legalities.  Most if not all DCC decoders have built in RF suppression so generally speaking if going DCC the old capacitor is no longer needed.
