They were looking at using the NMT vs the TRU on GEML, thats why they wanted the gauging clearance sorted.

I can't give you a definite answer. They shouldn't cause a problem. Theoretically you should be able to run every standard gauge train on every route, but some platforms are lower/higher and closer/further away from the rail than others. Some platforms may be tighter than others, and it would...

Taken in 1997? It may have been cleared back then in RailTrack days, but I know for a fact that the 43 is not Route Cleared on the LTN currently. @Yorkie, the route clearance process takes into account the suspension characteristics of every vehicle, the length of the vehicle profile, the...

Gauge clearance is all done in house. Its Network Rails job to assess gauge clearance for existing and any proposed vehicles to use the route. The class 43 is not cleared on GE, at least on the LTN (London to Norwich), because I was the guy trying to get it route cleared. Massive undertaking...

Its not the condition of the infrastructure that holds back the introduction of new rolling stock, its the clearance issues. Its very difficult to get new rolling stock introduced on a line. You need to survey every structure on that route and determine whether it will be safe to run the new...

Rail wear probably, the sound of the wheel flange wearing on the side of the rail. Depending on how fast the train is travelling effects what sound is made. Slow moving trains make a low pitch sort of groaning sound, faster trains make a higher pitched sound.

I think I saw that going past me on track today. Was heading North from Euston. Had a few Mk 1 coaches, a NR Yellow coach and a diamond jubilee class 67?

A TSR is published in the WON (Weekly Operating Notice) but not in the Sectional Appendix, therefore its not permanent and can be removed effectively anytime. However if the TSR is removed before its published end date in the WON its called a SPATE (Speed Previously Advised Terminated Early)...

Ultrasonic test and remove within 7 days is probably right.

Tamper.

Romford has its own sidings connected to the GE main line. It is used to stable tampers, MPSB's, OLE train etc...

It night not be a complete closure. Speaking from maitenance side the coping stones may have been removed becuase the clearance between the platform and the train may have been too tight and the easiest way to remedy this is to remove or cut back the coping stones rather than mess around with...

They are used to ensure track circuit.

Just a quick heads up. We have just had this posted on our internal news pages. Network Rail have produced some engineering videos. www.youtube.com/networkrail I can't post the link as I can't get on youtube from my computer at work. SOme of you might be interested.

You might be seeing the result of rail lubrication systems. On the transition to a curve we put rail flange lubricators on the gauge face of the rail to prevent the wheel flange from rubbing against the gauge face of the rail. Sometimes these become over active and can spew out grease. This then...

Well this is a stupid thread. How is it Network Rails fault that the snow caused signalling failures and are you saying that we have points failures at liverpool street on purpose?

If there is S&C nearby then I would imagine they are sleeper numbers. Obviously when laying sleepers with cast fastening systems such as cast pandrol fastenings in concrete sleepers, it is necessery to number the sleepers throughout the S&C and leading up to the S&C.

Ill have a look at my sectional appendix tomorrow night. See if I can figure out.

They are called 'Datum Plates'. They are used to moniter the relative movement of the track in relation to adjacent structures. Top left number is the number of the datum plate, one below is is the Lateral Offset to the plate. i.e. The distance, in milimeters, from the structure to the running...

That wont happen. In our contract it states that if there isn't a job at the 'assessed' compentency level, then one will be created for us. So long as we are looking for a job in the mean time.
