Cabinet of Ministers Regulations No. 214, Riga, June 29, 2004 (pr. No 39 22) methodology, the importance of strategic and regional rail infrastructure categories to be Issued under the Railway Act, article 7 of the second part of rule 1 defines the methodology by which the strategic and regional significance of the railway infrastructure (railway infrastructure) may be divided into categories, in order to guarantee the safety of train movements. 2. in the light of the freight and passenger transport, meaning the economy and speed of the trains, the railway infrastructure shall be divided into the following categories: 2.1 class I rail infrastructure-rail infrastructure of strategic importance for the precinct in which the cargo turnover exceeds 15 million gross tons per year and passenger train speed exceeds 120 kilometres per hour;
2.2. Category II rail infrastructure — not according to class I, the strategic relevance of the railway infrastructure and the regional district of the railway infrastructure of the circuit mean that cargo turnover is from 5 to 15 million gross tons per year and passenger train speed is between 80 and 120 kilometers per hour, as well as rail infrastructure, which runs the station in suburban electric trains;
2.3. Category III rail infrastructure — all other regional meaning infrastructure rail station. 3. The category of railway stations is set for technical equipment, as well as certain operational and technical requirements. 4. Class I railway stations are: 4.1, weighing 60 kilogram per metre, on concrete sleepers and with flexible blade switches with krusteņ mark acceptances of not less than 1/11 main and passable in the roadway. All engineering construction ensures train passes without movement speed limit;
4.2. signal and switches or automatic locking dispečercentralizācij with locomotive automatic alarm and signal and switch electrical control stations;
4.3. bilateral power goes by two independent mutually reserved powerlines from independent power sources (if necessary, also be autonomous emergency power supply);
4.4. communication and automation of cable lines;
4.5. automatic devices, with which the train in motion-controlled heating. 5. Category II railway stations are: 5.1 tracks, with a mass of at least 50 kilograms per metre, on the concrete or wooden sleepers and crossings transferred with krusteņ mark of not less than 1/11 main and passable in the roadway. All engineering construction ensures train passes without movement speed limit;
5.2. signal and switches or automatic locking dispečercentralizācij with automatic signalling of locomotives or semi-automatic locking with signals and switches of electric control stations;
5.3. the utilities by bilateral two independent mutually reserved powerlines from independent power sources (if necessary, also be autonomous emergency power supply);
5.4. communication and automation of cable lines;
5.5. If necessary, automatic devices, with which the train in motion-controlled heating. 6. Category III railway stations are: 6.1 Rails weighing 50 kilograms per metre (allowed to use also the rails with less mass per metre), to the concrete or wooden sleepers and crossings transferred with krusteņ mark of not less than 1/9 the main roadway. All engineering construction ensures train passes without movement speed limit;
6.2. semi-automatic locking with signals and switches the electric centralization or station lock with manual switches. You may use the elektrozižļ system or other simplified organisation of train movements. 7. If category III railway station need to be fitted with power supply, communication and the automated lines, railway infrastructure manager shall adopt appropriate decisions. 8. Be declared unenforceable in the Cabinet of Ministers of 20 October 1998, the provisions of no. 410 "methodology of strategic and regional significance for allocating railway infrastructure categories" (Latvian journal, 1998, nr. 308).
