I went to a talk with the network rail PM and he said it had been discounted due to the gradients over riccarton. Freight can still go via dumfries and across glasgow to the central belt. much of the design is being completed i understand. The scope includes laying the track with clearance...

ahh good old sketch up makes every building look the same. I like the glazing and concourse. Building looks like any other office block built in the last 10 years

I believe its track clearance for catenary. The track bed would need to be lowered for traditional catenary in the tunnel due to gauging issues. Difficult on a 4.5mile long tunnel. In the mound tunnel in Waverley they used an overhead rail system to deal with this, i dont know if this solution...

i am civil engineer and technically it is not really a problem connecting belfast with stranraer however practically it would be very expensive for the following reasons: The deep beaufort channel is in the middle and with the gentle gradients required to get to the required depth below sea...

I dont think anyone here thinks acquiring new cutting edge intercity rolling stock is a bad idea it is just IEP is crap. Its a bad and expensive concept. Its not Hitachi's fault its the DFT for putting stupid specifications and coming up with the idea of hybrids. it has been taken apart by...

also its quite err a channel 5 documentary. IE appeals to the lowest common denominator and trys to jazz it up with dramatic music and nail biting cliff hangers like: will the pantograph rise? Apprantly many ideas like zig zag catenary, grapite strips on pantographs, sound baffles on tunnels...

does extending the electrification to swansea mean IEP hybrid will be canned (fingers crossed!)

On a slight aside what do you think the Meridians could be cascaded to? My thoughts would be replacing Edinburgh glasgow-Aberdeen Inverness with them, its an intercity route not a turbostar route. Kill IEP and use meridian on the south devon lines? Marches line?

technically its pretty interesting line, its flat down the main valley through fresno and bakersfield so line costs are cheap. Passing over the Tejon mountains into LA is the big problem the freeway goes over the mountains. Apparantly they cant tunnel under it because of the st andreas fault...

King horn tunnel on the edinburgh dundee line on the north side of the forth has a kink and 40mph limit in it.i did surveying the old fashioned way with theodilite and chain s at college if you are meticulous the accuracy is mms.......but I wasnt!

I am tinkering with building a route and my be said not finding railworks too intuitive Can anyone help on a couple of points. If i use assets from other routes (freeware or Kuju of course) does friends i give the route too have to have them installed as well or can i package the assets up...

Tin rocket well its easier to construct a viaduct of harringworths length nowadays. all those bricks for a arch viaduct, that's a lot of hands on work! nowadays it would be a concrete balanced cantilever structure with spans between piers of 50-100m long. I was searching for costs for...

Here is a manufacturers brochure for the loco. I would concur is a updated version of a 67, with freight and 125mph passenger options. its total weight is 10t less than a 67 so hopefully they dont have the same route availability issues.

Hmmm yes slower over the WCML than a pendolino but not as much as you think. obviously they have a non tilt penalty but that is 10-15mph on corners. however Pendolinos are heavier due to all that tilt technology therefore HS2 will probably have better acceleration. i read somewhere that they...

HSTEd/ LE Grays Japanese Shinkansen services are 3x2 and pretty spartan and because the legroom is so generous i didnt really mind. Shinakensen stations look like bristol parkway!!! But they are clean and efficient. Grand stations in all the major HS2 cities would be nice but i am quite...

Bombadier suggested the concept as obviously its a cheaper alternative than the hybrid IEP. Also after 'Derbygate' and the thameslink rolling stock bunfight chucking Bombadier a hybrid voyager upgrade would be a way of keeping litchurch lane open seeing as there are no new rolling stock...

All-time:- Diesel loco: Class 47 simple styling but looks great Electric loco: Class 90. (international DB Class 103) DMU: class 165/166 networker EMU: Class 332/333 Heathrow Express stylish front end, looks aerodynamic. (International: 500 series Shinkansen, looks like something from the...

Couldnt help but giggle. THis one really is a pipe dream. The amount of track to be laid either side is huge. It connects onto the BAM (line around the north of Lake Baikal) which was started in 1943 as a secondary trans siberian away from the chinses border and it eat up money for 60 years...

technically no reason why a you couldnt build a tunnel to N Ireland. The is no particular geological problem as far as i know. The Beaufort channel is deep but the Seikan tunnel goes down 1500ft. THe sea is only 14miles wide between Honshu and Hokkaido, the length is due to the shallow gradients...

if thats true then its bloody depressing and pretty much sums up why politicians have the reputation they have got. Adonis pays Atkins to to do a detailed study including the M40, M6 and WCML corridors and produce a outline route. Adonis accepts the current proposed HS2 route and promptly...
