Or will they adjust the trams to suit the rails? They only concreted those rails in the last two weeks. I cant see how its possible to adjust the rails without breaking up the concrete and even then the rails are all bolted down so not sure how its even possible. Sure we will hear soon but my guess is they will have to change both rails and wheels on the Trams. Pretty sure theres no membrane on the rails still.

" So did they choose this curved section of track because they knew there was a spot on it where the gauge was too tight, or are there potentially innumerable spots along the newly laid track that are too tight that they don't know about?

WTF Posted May 20, 2022 Share Posted May 20, 2022 (edited) the real question is why wasn't the gauge tested BEFORE the concrete was laid ??? thick useless cunts................ i bet they didn't gauge widen to compensate for the sharpness of the curve.

Omobono Posted May 20, 2022 Share Posted May 20, 2022 you would have thought the contractors or even the DOI would have had a small bogie with wheels set to the 3 ft gauge ,that they could move along by hand and test the gauge as the work progressed , , there is a bogie in the tram shed ,with a spike that they used to use for clearing out the channel in the rail after the winters storm deposits , not rocket science all done before on a regular basis for almost 130 years , 1 Quote Link to comment Share on other sites More sharing options...
Ghost Ship Posted May 20, 2022 Share Posted May 20, 2022 That doesn't sound very modern or cutting edge though. Even if it has worked satisfactorily for 130 years... Quote Link to comment Share on other sites More sharing options...
doc.fixit Posted May 20, 2022 Share Posted May 20, 2022 Interesting that the BBC TV city comment was only a very long shot and the other picture was of the newly painted Villa railings. Wonder how they missed the rusty, twisted seaside railings? Quote Link to comment Share on other sites More sharing options...

However it was only very short in length so I'm guessing it wouldn't show up the issue with the curve in the track over the length of a actual tram. The other worrying thing was the guys there were physically pushing the tram around the tight bend despite the horse being harnessed up.

Andy Onchan Posted May 20, 2022 Share Posted May 20, 2022 I'm confused.... so are the rails not the same distance apart all the way along the curve?? Quote Link to comment Share on other sites More sharing options...

Yes but as there fixed the wheels wont deal with what in affect is a sharp change in direction . The predominant action will to go straight driven by the wheel sets but the rails are curved. Hence the jamming and the derailing. Quote Link to comment Share on other sites More sharing options...

Wow...did you not see the rail guys pushing the tram !!! They can be pushed easily by one man and in fact once running momentum keeps them moving. The horses are not struggling or exerting to carry out the task. There bred as work horses and only do a couple of trips before being changed. 1 Quote Link to comment Share on other sites More sharing options...
