Was at Euston Square station around 4pm today, when a westbound train (a unit containing car 24021 I think), pulled in making a motor sound, very different from a S stock, much more akin to an Electrostars sound I thought. Also, I confirmed I wasnt hearing things because immediately after the Weird Westbounder stopped, my Eastbound S-Stock pulled in!
I digress.
But, does anyone have a clue what could have been the case for the weird sound?

It could be any number of things, and would be quite hard to suggest without hearing it.
However, it's worth noting that 21099/100 has a distinctly different whine from the rest of the S stock - as the prototype unit it has a different set of motors. It's much higher pitched, and very noticeable.

There is also another S Stock which seems to have something loose under the solebar, as it makes a dragging sound when it pulls away. I've seen it on a few occasions but haven't been able to note the number. The noise is quite distinct, and very different to the whine of the motors or the scraping sound of the shoegear. Very strange

I wasnt aware of its existance so the sound of its approach to Euston Square had me scratching my head. |

Very strange It may be the lube sticks that are fitted to the S stocks to help ease the wearing of the rails they are designed to move in there holders |

Yes heard this on a number of units too. Almost like a dragging/vibrating sort of thing.
