b'If the Secretary of State is satisfied with respect to any local authority aerodrome that it is necessary or expedient that the local authority maintaining the aerodrome should be empowered to carry on in connection with the aerodrome any ancillary business which the authority would not otherwise have power to carry on, he may make an order authorising that local authority, subject to such conditions (if any) as may be specified in the order, to carry on that business in connection with the aerodrome. Public transport 11.4 Section 101 of the Road Traffic Act 1930 (as amended) enables a local authority (which includes district councils, joint boards or joint committees) who, under any local Act or Order, are operating a tramway, light railway, trolley vehicle, or omnibus undertaking to, as part of the undertaking, run public service vehicles on any road inside or outside their district. This section is subject to certain exceptions, but under section 104 a local authority authorised to run public service vehicles under the Act may demand and take for passengers and parcels carried on such vehicles such fares and charges as it thinks fit. Section 105 enables neighbouring authorities having such functions, and any other person not being a local authority, to make and carry into effect agreements for the management, working and maintenance of any service which any party to the agreement is for the time being authorised to run in the district. Such agreement may make provision (amongst other things) for: (a)the working, user, management and maintenance of any vehicles, lands, depots, buildings, sheds, and property provided in connection with any services to which the agreement relates by any party to the agreement and the right to provide and use the same and to demand and take the fares and charges authorised in respect of such services; (b)the supply by any party to the agreement of vehicles and conveniences in connection therewith necessary for the purposes of such agreement and the employment of officers and servants; (c)the through running of vehicles. Section 46 of the Public Passenger Vehicles Act 1981 enables a local authority to use a school bus, when it has been used to provide free school transport, to carry as fare paying passengers persons other than those for whom the free school transport is provided and to use the school bus belonging to the authority, when it is not being used to provide free school transport, to provide a local service. Non-metropolitan districts also have a similar power under section 63 of the Transport Act 1985 (the 1985 Act). For these purposes, county and district councils have powers to enter into agreements providing service subsidies, but only where the service in question would not be provided without subsidy, and provided that open and competitive tenders are invited for the provision of such service. Note though that section 63 has been amended due to the repealing of subsection (3) and the amendment for subsection (5) pursuant to the Transport Act 2000, Local Government in Scotland Act 2003 and Local Transport Act 2008.
