    What are most trains made out of?

    In general, passenger train bodies are, these days, made from aluminium with some steel parts. Bogies are always made from steel although there are experiments going on with a bogie frame made from carbon fibre. Wheels and axles are always steel. Locomotives are almost always made from steel...

    How long will it take Avanti to tidy up after Virgin?

    It would be good if Avanti would tidy up after themselves. Standard Premier has started, yet the coaches are still marked 1st class. Only the antimacassars have been changed. I wonder whether this accounts for the small numbers in that accommodation?

    Leaf fall- Dry Ice Experimentation on the Northern Network

    Those articles may not mention the benefit of the CO2 dry ice pellets turning to gas but the Professor in charge of the work certainly makes this point in his presentations.

    Best parking for Stanmore on a Saturday

    Beware of Stanmore car park if there's something on at Wembley. On those occasions it gets full.

    Central Line RAT trains

    You might like to sample the contents of the tanks on the LU RATs but I really wouldn't recommend it!

    HS2 Euston - number of platforms... again...

    The article bases everything on the nominal 25 minute turnaround time. If this is set in stone, then the logic of the article makes sense. It's also necessary to allow some wriggle room somewhere and other destinations have less wriggle room than London. The author cites Glasgow Central where...

    London Underground: Man died after falling into gap, RAIB finds

    Three points about gap fillers: 1) Those in New York are interlocked with the signals and have little rubber wheels so that the train will push them back slightly until the track circuit that triggers retraction is occupied. 2) The victim at Waterloo wasn't adjacent to a door when he fell in...

    Wheel flange

    For the sake of completeness, a very small number of cable hauled railways - funiculars have wheelsets with a flange on the inside and outside of one wheel and no flanges on the other. on funiculars with two vehicles balanced via the rope, this system allows the cars on a single track to pass at...

    TfL Rail service from heathrow nonnstopping after 4 minutes of delays

    It also depends on the rules the controller was working to. It would be simple to tell MTR Crossrail that non-stopping booked stations is not acceptable. I have always thought that this activity only benefitted the TOC chasing performance stats that generally don't benefit the customers. As far...

    Nearly Caught Out by Expired Disabled Railcard

    The rail companies through the Rail Delivery Group recognised this issue, but it was at a time when they had to ask the government before doing anything that might have a cost. Extension of rail cards was deemed by DfT to have an unacceptable cost so permission to grant extensions was refused.

    How flexiable are LNR with 59 vs 60 minute delays for delay repay payouts?

    The arrival time is an estimate based on a) the actual time that the last track circuit before stopping at the station is occupied plus b) an estimate of how long it takes for the train to get from that location to the stopping position. At terminal stations, that estimate may or may not be...

    East-West Rail (EWR): Oxford-Bletchley construction progress

    What seems to be missing from the design is an entrance on the shopping centre side of the railway which would open up the station to "the other side of the tracks".

    Progress on Avanti West Coast's 805/807s Hitachi AT300 sets

    If I were the representing Avanti and/or the funder (ROSCO) I would insist on not accepting any units unless the root cause of the cracking is understood and resolved on "my" units.

    DfT To Negotiate 6/10-year Direct Awards for GW and West Coast Services

    The West Coast PIN document suggests a 10 year (120 month) term. It also has no information about the nature of the contract. The key difference between the former Avanti contract and the future in GBR is about which party bears revenue risk. Do they return to the former arrangement where the...

    1972 tube stock replacement

    The hypothetical modifications to make a 2009 tube stock suitable for the Bakerloo line would have been mainly to the carbody to accommodate the slightly smaller tunnel, changes to the underframe to accommodate a larger bogie rotation and probably changes to inter-car jumpers. These...

    World's most complex trackwork?

    Grand Central Terminus is certainly an impressive place. With something over 30 platforms served by just 4 tracks, turning loops behind the buffers and something line 7/8 mile where the permanent speed restriction is 10mph leads to quite an operation.

    World's most complex trackwork?

    Lat time I travelled by train out of Zurich Hauptbahnhof, I was amazed by length of time spent passing marshalling yards, sidings and diverging junctions. Worth a look on Google satellite view.

    Incident at Chalfont & Latimer (21/06/20)

    The question of retracting tripcock arms on NR infrastructure comes up from time to time. The key issue is that the tripcock tester is far from being a complete test. As Dstock7080 says, all it does is check that the arm is in the right position and alignment. If the arm isn't in the right...

    HS2 Rolling Stock Tender

    When a large public procurement takes place, there is no place for emotion. The invitation to tender will contain the rules of the procurement and bidders and the client have to abide by the rules. To get a place on the bidder list, generally, companies go through a pre qualification stage where...
