Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a word-for-word translation like 'рельсовый детекторный автомобиль' which sounds unnatural. The accepted technical term is 'вагон-дефектоскоп' (rail flaw detection car) or 'контрольная тележка'.
Common Mistakes
- Writing 'rail detector' as one word (raildetector).
- Using 'train' instead of 'car' (it is a specific car, not the entire train).
- Confusing it with a 'diesel multiple unit' or other self-propelled passenger car.
