custom staff and barlines

[Gerard McConnell]

Hello,
How do I get barlines to appear in the following?

\version "2.12.0"
\layout {
    \context {
        \Score
    \remove "Bar_number_engraver"
    }
    \context {
        \Staff
    \remove "Clef_engraver"
    \override StaffSymbol #'line-count = #1
    }
}
\score {
    \new Staff
        \relative c' {
            \time 2/4
            b'4 b8 b | b4 b | b4 b8 b | b4 b \bar "||"  
        }
}

Thanks,
Gerard
