Following OMO conversion of the first few existing routes, LT developed a programme of converting parts of routes, or converting certain days of the week.  Most of the following routes fall into this category, although the 136, 284 and 233 were all new routes, in each case using a single bus, at least in their initial phase.  The 284 and the 233 were later to become operated by the FRM.
