Wait till LTA build a lift or ramp from ground level to the
interchange 1st...
But then, WLDEP can take in OC500LEs for services like 171 which
is going to be WAB soon. Others can be deployed to services like
61, 167, 859 etc.
Its going to be a lift, which i heard.
And SMRT is going to bring in another 63 WAB buses
starting from June, next month. Probably is what Tamago said,
OC500LEs. So, a total of 130 OCs.
