this was followed by the albula line in 1903 and the series of expansion projects carried on until 1922 . all rhb lines are 1 000 mm 3 ft 3 3 8 in metre gauge wide metre gauge and electrified 61 km 37.9 mi the bernina railway from st moritz to tirano is electrified at 1000 v dc . 321 km 199.5 mi is electrified at 11 kv 16.7 hz including since 1997 chur arosa and the new vereina tunnel . the network contains 84 tunnels the longest being the 19.042 kilometre 11.832 mi vereina tunnel opened on 19 november 1999 and the 5.864 kilometre 3.644 mi albula tunnel and 383 bridges . the maximum gradient is 7 % on the bernina railway 2 6 % on the chur arosa line and 4.5 % on landquart davos line . network edit current passenger services as operated by the rhb 2016 service timetable route notes re 910 landquart schiers klosters davos platz 1tph re 910 landquart schiers klosters zernez samedan st. moritz 1tp2h re 910 klosters davos platz 1tph winter seasonal service re 910 920 disentis must r railway station ilanz chur landquart schiers klosters sagliains scuol tarasp 1tph r 915 davos platz filisur 1tph r 930 chur arosa 1tph re 940 chur rh z ns thusis filisur st. moritz 1tph s1 941 schiers landquart chur rh z ns 1tph s2 941 chur rh z ns thusis 1tph r 950 st. moritz pontresina poschiavo tirano 1tph r 960 scuol tarasp sagliains zernez samedan pontresina 1tph in 2002 the annual traffic carried by the rhb was 300 million passenger kilometres and 54 million tonne kilometres of freight . 80 % of the passenger income comes from tourist traffic although 40 % of passengers are local commuters . landquart davos line edit ge 4 4 i with push pull train and two extra coaches shortly before arriving in saas . k blis is visible in the valley at left . landquart railway station in graub nden is the starting point of the rhaetian railway historically as part of the landquart davos line operationally as the company s main workshop and topologically as the 0 kilometre point of the company s core network . the landquart davos line is the oldest in the rhaetian railway network . after leaving landquart the line to davos crosses the river landquart and then generally follows the river upstream as far as klosters crossing the river several times along the way . just beyond klosters there are two tunnels . one of these is for the vereina line see below . the other the klosters loop tunnel takes the davos line at a 45 degree angle towards the west . the line to davos then loops back towards the east inside the cavad rli loop tunnel and continues through dense larch and other coniferous forests to the davos laret . the highest point on the line is the next stop davos wolfgang . then the line leads back down and along lake davos to davos dorf and the terminus at davos platz . davos filisur line edit the connecting line from davos platz to the albula railway at filisur passes through wild gorges and is technically very interesting not only due to its famous wiesen viaduct . the davos filisur line is 19 km 12 mi long runs through 14 tunnels extending a total of 4 200 m 13 780 ft in length and crosses 28 bridges . it was electrified in 1919 . landquart thusis line edit glacier express between reichenau tamins und bonaduz . starting in the rhine valley the landquart thusis line runs more or less parallel with the swiss federal railways sargans landquart chur standard gauge line as far as chur 585 m or 1 919 ft . the line to thusis then simply follows the course of the rhine to bonaduz 655 m or 2 149 ft . from there it enters the domleschg valley and follows the posterior rhine from rh z ns 658 m or 2 159 ft to thusis 697 m or 2 287 ft . albula line thusis st. moritz edit main article albula railway this line begins in thusis 697 m . it continues toward tiefencastel 851 m following the albula and then crosses the landwasser viaduct before arriving at filisur 1032 m . shortly after filisur the line passes its first spiral tunnel then continues to berg n bravuogn 1373 m . between berg n bravuogn and preda 1789 m at the end of the valley the line has to achieve a difference in height of about 400 metres inside a horizontal distance of 5 kilometres without using rack and pinion but with many spirals . then the line enters the albula tunnel at 1 815 metres under the albula pass . it emerges in the val bever where it reaches bever 1 708 m on the engadin plain . the line continues toward samedan 1 721 m and arrives at st.moritz 1 775 m . albula tunnel edit main article albula tunnel in 2009 it was announced that an examination of the albula tunnel conducted in 2006 had found major degradation of the tunnel with over 60 % of the lining in need of replacement . furthermore the bores are small by modern standards and cabling signalling and drainage all need replacement . as a result it was announced that an inquiry would decide from two options a course action ; either comprehensive renewal of the existing tunnel or the construction of a new bore to modern standards . 3 on the result of this inquiry rhb has decided to build a new tunnel . construction should begin in 2014 . reichenau disentis must r line edit two glacier expresses coupled together run through the rhine gorge . the reichenau to disentis must r line links the rest of the rhaetian railway network with the matterhorn gotthard bahn . it branches from the line to thusis behind the shared rhine bridge . the line was opened progressively between 1903 and 1912 and has been electrified since 1922 . in contrast with the accompanying road which rises about 500 meters towards flims and laax the railway to disentis must r runs slowly up the narrow ruinaulta gorge . on this part of the line its associated engineering structures dominate the otherwise pristine natural landscape . at ilanz the railway line and road merge paths once again . their combined pathways then rise slowly and evenly to disentis must r. the main traffic on the reichenau disentis must r line is regio express passenger trains operating at hourly intervals . several times a day there are glacier express trains in each direction . timetabled goods trains also operate on the line to serve industry in the vorderrhein area and supply cement for the construction of the normal gauge gotthard base tunnel with train ids starting with 5 . usually three pairs of trains serve disentis must r with a ge 6 6 ii and a few additional trains go only to ilanz with a ge 4 4 ii . engadin line pontresina scuol tarasp
