Why is the central line noise so extreme, particularly between Stratford and Mile End. The noise is usually very high pitched , far louder than any other line and really hurts your ears. Does anyone know what causes the noise and do drivers hear this noise too?

It went with extremely lively riding, as well. All good fun for a lad just coming into his teens! |

I don't travel on that part of the line, but generally noise is due to wheel to rail interfacing when it comes to curves. The flanges on the wheels rub but whether this is the noise you hear, I have no idea.

It went with extremely lively riding, as well. All good fun for a lad just coming into his teens! That is (I think) the longest journey between stations on the deep level tube section of the system. As its also fairly straight (if there are any curves they are gentle) the trains travel at "full pelt". In the days of the 1962 tube stock the hanging hand-grabs would swing furiously, sometimes with the ball at their outer end reaching the train's ceiling. I usually travelled in the front car and upon surfacing at Stratford it sometimes seemed as if we were travelling at the same speed as the mainline trains.... alas only for a few seconds as the train soon slowed down to stop. That is except for days when the station was closed and central Line trains zoomed through without stopping. This was usually only on Boxing day, on one of the years when this happened I filmed this with a super 8 cine film camera. Simon |

[Stratford - Mile End] is (I think) the longest journey between stations on the deep level tube section of the system. According to CULG it is 2.77 km, of which 2.51km is underground (slightly less eastbound). The longest distance between seep tube stations is, I think, the 4.77km, between Heathrow T4 and Heathrow 123. |

I think that Finsbury Park to Seven Sisters is also longer than Mile End to Stratford.

The worst part I remember with the 62s was Liv St-Bank, where the screeching round the street-contoured curves was abominable.

I don,t remember the 62ts being anywhere near as noisy as the 92ts. I commuted on the 62,s for a couple of years before becoming a guard on them. Did the 92ts get smaller wheels and if so could this be one of the reasons why they make so much more noise, even when the track is relatively straight?

I never liked the Central line from the start. Even though I've been regularly using the Tube only for a few years. But in the summer it's the absolute sweat gland of the network, the 92ts always seemed noisy, rattling, tired and in need of a refurbishment. Or has it become like that only lately?
