What are S stock brake blocks made of? In our metro, brake blocks are made of plastic composite of sorts, so burnt plastic smell after heavy pneumatic braking is normal.

it was caused by a timetable edit that set up a never ending run of route reservations which overwhelmed the system causing it to give up and shut down Note to programmer: watch for the possible infinite loops .

Also, I didn't point it out earlier but I love how the text on my picture was edited to make it seem like the lift only went to a single platform. And a strip colour was changed from orange to red.

I only intended to run it for a month. February is the 14th anniversary of that month... Nothing is more permanent than the temporary.

I hope the time allowance for automatic unlocking is sufficient for the driver to stop the train in normal (non- emergency) way Is it really necessary to allow external access while train is in motion?

Is this train a vintage train, a heritage train... or a legacy train? It is an old train .

treat all rails as live and not stand on It is advised to avoid standing on the top of any rail. Reason: you can easily slip and fall. Step over them.

I wasn't able to find a definitive list of what animals that zoo has. I could not do that, too, but zoo reviews mention pygmy marmosets, so I think you are right . Picture must be deceptive. Marmosets are about the size of an average hamster. 4.6 to 6.0 in, according to Wikipedia.

The clue is in the name- Light Emitting Diode Although LEDs are diodes, their maximum reverse voltage is very low, typically 5 V, so they are not normally used as rectifiers. I think the clue is in the fact it is labelled for 80-100V AC. They would light if inserted back to front. They must have a bridge rectifier inside .

they have been making a lot of adjustments to platform edges to suit the new trains Just out of interest - what is special with new trains that requires platforms' adjustments?

Tallinn has only trams, no metro Yes, indeed . The trickiest metro system I have used so far is the St Petersburg one - the stations all have platform edge doors Not all, only 10 out of 67 stations on lines 2 and 3.

I don't think the Wikimapia link to the Black Sea coast is relevant. It IS relevant because it shows the exact location of the monument .

Power on the Underground does fluctuate and could well make clocks show inaccurate time. Can't help wonder why...

Imagine the frequency you could run without passengers getting in the way! 48 tph with conventional colour light signalling. Probably more using advanced stuff . When trying to run such a high frequency service with any degree of reliability, it will come down to seconds here and there. And you'll have to avoid delays like plague.
