2. Hka htung lam gaw gara Grade rai ta?

Railroad lam ni hpe cyclic loading npu hta grai ngang grin na matu engineering galaw da ai wanleng n-gang- ngu shamying ai n-gang langai kaw na galaw ai. Masha law law lu ai jahpan ni hta:

3. Wanleng lam hkawm ai lam ni hta n tara ai lam ni gaw n tara ai kun?

Yes- gaw wanleng lam ntsa hta arai ni hpe tawn da ai gaw tara upadi shagu hta tara n shang ai. Ndai hta gumhpraw, tinang a arai ni, shing nrai ahkang n lu ai htu shaw ai arung arai ni lawm ai. Hpa majaw rai?

Dai gaw afederal maraUS Code Title 49 a npu hta FRA kaw nna hkan sa ai.
Dai gaw, wanleng lam galaw ai ni, hkrunlam hkawm ai ni hte mung shawa ni hpe hkrit tsang shangun ai.

4. Metal Ralinging de Drill galaw mai na kun?

Yes- raitim, ladat gaw ahkyak ai. Lam ni a makau kaw nga ai metal railings (ga shadawn, platform pat shingdang ai lam ni, signal brackets) ni hpe aluminum, n-gun n rawng ai n-gang, shing nrai, galaw ai magri ni kaw na galaw ai. Hkamja lam hte htu na matu:

5. Ties & Spikes a matu kaja dik htum Drill galaw ai

Wanleng lam ni (Sleepers):
