Common Rejection Reasons
RPF/RRB strictly rejects block-letter or all-capital signatures — running/cursive handwriting is required.
Specs have shifted between cycles before (e.g. RPF Constable 2019 allowed 30-70KB vs the now-standard 20-50KB) — reusing an old prepared file without checking the current notification can cause rejection.

RPF (Railway Protection Force) Sub-Inspector recruitment runs on the same centralized RRB application infrastructure as NTPC and Group D, sharing the same photo (20-50KB) and signature (140×60px, 10-20KB) specification. RPF/RRB requires running/cursive handwriting for signatures — block letters or all-capital signatures are strictly rejected. Note that specs have shifted between cycles before (e.g. RPF Constable 2019 allowed 30-70KB, while recent cycles standardized to 20-50KB), so always confirm against the current notification.
