... on a 99 mph route. Doesn't apply to 124, 143 or 186 mph routes.
No, you are not allowed to go faster than 99 mph! You'll need LZB to go faster than 99 mph, and that means electronic controlled acceleration and braking controls - very unlikly to get a steam engine fitted with that!
So your speed limit is set to 160 km/h... that's why even modern ICE trains of germany only travel 160 km/h (99 mph) if the LZB controls fail... because with PZB you are only allowed to go 99 mph... sorry, it doesn't matter if you have a track construced and allowed for 186 mph or 124 mph...you are not allowed to go faster than 99 mph without LZB
The fastest recent steam speed record in Germany is ca 99 mph though (last: privately owned DR 18.201 in 2011).
Well, no... the latest record is 101 mph.
18 201 never run faster than 99 mph after it's private ownership, because the load and gear problems made it nearly impossible to go faster. It's 112 mph record was only done light engine on the czechian speed ring... many dream of leting the engine run faster, but the E41 boiler won't be able to deliver the steam neccessary for those speeds, as the BR61 running gear isn't able to widstand this speed - as to generate this power for those speeds.
And today, 18 201 won't go faster as 99 mph, because it has no equipment with LZB - so speed is limited to 99 mph, even if the engine has admission to run 112 mph from construction - but in service, it is only allowed to go 99 mph
But if say VM Nürnberg refurbished its museum DR 05.001 steam engine and let her out they could make her do her 124 mph - as long as the track's rated for that.
No. 99 mph limit. Because you have to equip 05 001 with LZB, very unlikly to happen, because as mentioned above, you need electronical control of throttle, gear and brake for LZB... even if the engine has the contructional admission for 108 mph. The 124 mph was a record on closed track, and it was finished by a radio signal from the dynamometer car behind the engine - because the measurement gear in the car wasn't able to measure greater speeds and the staff has serious worries about stability of the car running those speeds - 05 001 wasn't going top notch, but it was traveling on sprint. she could travel faster, but only short distances in sprints, top speed to hold without sprint was the 108 mph - that's why they gave 05 series only constructional admission for 108 mph, and not 124 mph
Allways keep two-thrid level in gauge and a well set fire, that's how the engineer likes a fireman
