			The '''top row''' shows, from left to right, the '''distance to the next monitoring point''', the '''target speed (vZiel)''' – i.e. the speed that must be reached at this point – and the '''current speed limit (vSoll)''', which is '''dynamically adjusted''' by the system.

			When the speed is increased, the '''new speed only applies once the monitoring point has been passed'''.

			'''IMPORTANT:''' vSoll depends on '''various factors''' and may differ from the '''maximum speed limit currently displayed in the game'''. '''vSoll is ALWAYS the maximum permissible speed''' – regardless of the environment.

			The '''second row''' shows the '''current operating status of the LZB'''.
			'''‘B’''' stands for '''operational readiness''',
			'''‘Ü’''' indicates that there is an '''active transmission''' between the vehicle and the route control centre,
			and '''‘ENDE’''' signals the '''initiation of the LZB end procedure''', during which '''LZB monitoring is terminated'''.

			The '''third row''' contains the '''LZB indicator lights''':
			'''‘G’''' indicates that the train is '''travelling too fast''' or '''approaching a braking point''', and a '''warning is active'''.
			'''‘H’''' indicates that the train has '''passed a stop point'''.
			'''‘S’''' signals that '''emergency braking has been initiated''' if the LZB specifications are not being complied with.

			'''IMPORTANT:''' A '''speed violation indicated by ‘G’''' does not result in an emergency brake application, but rather in a '''service brake application'''. In this case, '''‘S’ is not active'''.

			The '''fourth row''' contains '''special operating indicators''':
			'''‘Bef. 40’''' stands for a journey on special orders with a '''maximum speed of 40 km/h''',
			'''‘Stör’''' indicates an '''LZB fault''',
			and '''‘1000 Hz’''' represents another function – implemented as a '''special display in the HUD'''.

			It should currently be noted that '''passing an LZB stop''' – during which the indicator lights '''H and S''' (and possibly others) would normally activate – is '''not yet implemented'''. '''Driving with a fault''' in the LZB system, for example in '''‘Fault’ mode''', is also '''not yet supported'''. However, '''both functions are already in planning''' and will be added in the future to '''further complete the system'''.
			'''The HUD is only visible in the driver's cab.'''

			The HUD can be switched between '''German''', '''English''', and '''off''' using the '''‘Ditchlight’ button''' ('''left radial menu, 4th button from the bottom'''). This function has been '''specially reprogrammed''' for this purpose. However, the '''language change only works''' if the programme can '''provide the necessary resources''' in the background. Only the '''terms are translated''', not the entire user interface.

Overall, LZB is a '''key element''' for the '''safe and efficient operation''' of modern high-speed trains and forms the '''basis for many high-speed lines in Germany'''.

			The '''LZB developed by 3DZUG for iOS and Android''' is a '''real milestone in the world of mobile railway simulations'''. Such a '''realistic implementation of train control''' has never before been seen on mobile platforms – neither in terms of '''scope''' nor '''precision'''. Our goal was to make the LZB not only '''functional''', but also as '''realistic as possible''', both '''technically''' and '''visually''' – and to do so despite the particular challenges posed by '''mobile devices'''.

			The '''adaptation to the limited screen size''' and the wide range of '''display resolutions''' of modern smartphones was particularly challenging. In order to ensure '''clear and intuitive usability''', we developed our own '''HUD (head-up display)''' in addition to the classic integration in the '''virtual driver's cab'''. This HUD is an '''additional display layer''' that '''graphically displays important information''' such as '''target speed''', '''destination distance''', and '''warning messages''' over the image – regardless of the '''viewing angle''' or '''zoom factor''' in the cab. This means that the LZB remains '''visible and usable at all times''', even on small screens, without compromising '''immersion'''.

			With this solution, we have succeeded in implementing a '''complex high-speed safety system''' such as the LZB on mobile devices in a way that is not only '''technically functional''', but also '''user-friendly''' and '''visually appealing''' – a '''novelty in mobile simulation'''.

			An '''important note on how our LZB works on mobile devices''': Unlike in real life, our LZB '''does not automatically increase the speed''' when the permitted speed – the so-called '''vSoll''' – increases.

			The reason for this is a current '''technical limitation''': A fully-fledged '''AFB (automatic driving and braking control''', i.e. a kind of '''cruise control''') is currently '''not yet feasible in mobile simulation'''. In reality, the AFB would '''automatically increase the power''' in conjunction with the LZB to reach the new speed.

			Our LZB, on the other hand, '''dynamically adjusts the target speed (vSoll)''', '''continuously monitors the current speed''', and '''reliably protects against exceedances'''. However, the '''power must be increased manually''' and the new speed reached by the player (train driver).

			This deliberate decision allows us to implement a '''realistic simulation of LZB monitoring''' despite technical limitations – with '''authentic behaviour''' in brake monitoring and speed adjustment. At the same time, the '''interactive driving experience''' is retained, with the train driver '''actively maintaining control''' over the train's power.
